north carolina class battleship vs iowa class

He also suggested Terrier or RIM-8 Talos launchers to supplement the AA guns and proposed nuclear (instead of conventional) shells for the 16-inch guns. Along with many other provisions, it limited all future battleships to a standard displacement of 35,000 long tons (36,000 t) and a maximum gun caliber of 16-inch. As designed, the crew complement was 1,880 with 108 officers and 1,772 enlisted. This design was later revised to accommodate the Polaris Fleet Ballistic Missile, which in turn resulted in a study of two schemes by the SCB. At 35,000 yards (17 nautical miles; 32 kilometres), a shell from a 45 cal would strike a ship at an angle of 45.2 degrees, as opposed to 36 degrees with the 50 cal. [151] In 1991, Wisconsin participated in Operation Desert Storm, firing 24 Tomahawk Missiles at Iraqi targets, and expending 319 16-inch shells[143] at Iraqi troop formations along the coast. A 660 lb (300 kg) warhead hit on the port side 20 ft (6.1 m) below the waterline at a point that was just behind the number one turret. With regards to the treaty limits, the design had an extremely comfortable margin with a standard displacement of 31,750 long tons (32,260 t). Despite this increase, the maximum speed for the ships did not change, since the modifications to the powerplant were incorporated later in the design process. ^ Kentucky was not officially launched; her hull was moved from drydock to allow Missouri to be admitted for repairs following her grounding. The guns weighed 192,310 lb (87,230 kg; 86 long tons) not including the breech; the turrets weighed slightly over 3,100,000 lb (1,406,136 kg; 1,384 long tons). Further suggestions were made to convert Kentucky into a specialist anti-aircraft ship, and work was again suspended. 1944 – USS, Treaty for the Limitation of Naval Armament, Top Ten Fighting Ships; North Carolina class battleship, List of battleships of the United States Navy,, World War II battleships of the United States, Creative Commons Attribution-ShareAlike License, 17,450 nmi (20,080 mi; 32,320 km) at 15 knots (17 mph; 28 km/h), Struck 1 June 1960; Sold for scrap, 24 May 1961, McBride, William H. "The Unstable Dynamics of a Strategic Technology: Disarmament, Unemployment, and the Interwar Battleship. The extension of the armor belt to the triple bottom, where it tapers to a thickness of 1.62 inches (41 mm), serves as one of the torpedo bulkheads and was hoped to add to protection. After the official surrender, these men were brought back aboard and the battleship sailed to Okinawa. The vessels that eventually became the Iowa-class battleships were born from the US Navy's War Plan Orange, a Pacific war plan against Japan. These were not installed because it was estimated that the conversion would delay completion of the ships by 6 to 8 months. The lower spaces contain rooms for handling the projectiles and storing the powder bags used to fire them. The contract design displacement subsequently stood at 45,155 long tons (45,880 t) standard and 56,088 long tons (56,988 t) full load. Although crews on both ships frantically tried to avoid the other, it was to no avail; Washington gave Indiana a glancing blow, scraping down a large aft portion of the ship's starboard side. A month later, the SCB chairman voiced his belief that the North Carolinas and South Dakotas would be excellent additions to task forces—if they could be faster. By 1945, the considerable increase in anti-aircraft armament and their crew accommodations had increased full load displacement to 46,700 long tons (47,400 t), while crew complement increased to 2,339 with 144 officers and 2,195 enlisted. The subsequent Washington Naval Conference resulted in the 1922 Washington Naval Treaty. [92], The Navy considered several proposals that would have removed the aft 16-inch turret. A problem shared with its sister Washington and some other ships like Atlanta, it was only cured after different propellers were tested aboard North Carolina, including four-bladed and cut-down versions of the original three-bladed. [38] When firing the same conventional shell, the 16-inch/45 caliber Mark 6 used by the fast battleships of the North Carolina and South Dakota classes had a slight advantage over the 16-inch/50 caliber Mark 7 gun when hitting deck armor – a shell from a 45 cal gun would be slower, meaning that it would have a steeper trajectory as it descended. Following the bombardment of Okinawa, Missouri turned her attention to the Japanese homeland islands of Honshu and Hokkaido, performing shore bombardment and screening US carriers involved in combat operations. The battleship shot down a plane on the 7th and two on the 17th. This increased the price of the battleships to $60 million each, so the Bureau of Steam Engineering and Bureau of Construction and Repair recommended to their superiors that the $37 million tenders from the two navy yards be accepted. Although the ships were originally designed to carry only four quadruple 1.1 in and twelve .50 caliber, this was greatly increased and upgraded during the war. She set sail for the Panama Canal and the Pacific Ocean on 23 August and reached her destination, Tonga Island, on 14 September, where she became the flagship of Admiral Willis "Ching" Lee. However, this did not mean that it possessed inferior anti-air abilities. The front portion was 14.7 inches (373 mm), the sides increased to 16 in, and the rear portion reduced to 11.5-inch (292 mm). Each gun rests within an armored turret, but only the top of the turret protrudes above the main deck. The torpedo bulkheads were designed to elastically deform to absorb energy and several compartments were liquid loaded in order to disrupt the gas bubble. [N 9], The powerplant of the Iowas consists of eight Babcock & Wilcox boilers and four sets of double reduction cross-compound geared turbines, with each turbine set driving a single shaft. The United Kingdom was in the final stages of ordering eight capital ships (the G3 battlecruisers, with the first's keel laying in 1921, and N3-class battleships, to be laid down beginning in 1922). [N 4] During World War II, the draft was 37 ft 2 in (11.33 m) at full load displacement of 57,540 long tons (58,460 t) and 34 ft 9 1⁄4 in (10.60 m) at design combat displacement of 54,889 long tons (55,770 t). "A Comparison of Machinery Installations of, This page was last edited on 15 November 2020, at 06:57. Soon after the battle, the Japanese began evacuating Guadalcanal. Either their battleships would be built to have a, This change meant that the Bureau of Construction and Repair had to modify the design of the. As the war drew to a close, the United States introduced the SK-2 air-search radar and SG surface-search radar; the Iowa class was updated to make use of these systems between 1945 and 1952. [25][26][27], Although the Second London Naval Treaty stipulated that warship guns could be no larger than 14 inches, a so-called "escalator clause" was included at the urging of American negotiators in case any country that had signed the Washington Naval Treaty refused to adhere to this new limit. The armor belt extends to the triple bottom, where the Class B lower portion tapers to 1.62 inches (41 mm). [154] Eventually both hulls were scrapped. The two ships of the North Carolina class entered service in 1941. As a result of this shift in tactics, U.S. fast battleships of all classes were relegated to the secondary role of carrier escorts and assigned to the Fast Carrier Task Force to provide anti-aircraft screening for U.S. aircraft carriers and perform shore bombardment. The 5-inch gun turrets, along with their ammunition magazines, were armored with 1.95-inch (50 mm) STS plates. On 13 November, three formations of Japanese ships were discovered on course for Guadalcanal, one of them aiming to bombard Henderson Field while night gave them protection from aircraft. [139] During the Korean War, Iowa bombarded enemy targets at Songjin, Hŭngnam, and Kojo, North Korea. At the time of their commissioning, all four of the Iowa-class battleships were equipped with 20 quad 40 mm mounts and 49 single 20 mm mounts. Displacement would be lowered slightly to a fully loaded weight of about 41,930 long tons (42,600 t), while speed would not have changed. [53][54][55][56], After a shakedown cruise in the Caribbean Sea and participation in war exercises, North Carolina transited the Panama Canal en route to the Pacific War. [29] They also have excellent maneuverability in the open water for their size, while seakeeping is described as good, but not outstanding. At one point, the NATO Sea Sparrow was to be installed on the reactivated battleships; however, it was determined that the system could not withstand the overpressure effects from firing the main battery. [46], Each 5-inch/38 gun weighed almost 4,000 pounds (1,800 kg) without the breech; the entire mount weighed 156,295 pounds (70,894 kg). After World War II, Missouri conducted largely uneventful training and operational cruises until suffering a grounding accident. With an estimated range of 675 to 1,500 nautical miles (1,250 to 2,778 km; 777 to 1,726 mi)[99] for the Tomahawk missile and 64.5 to 85.5 nautical miles (119.5 to 158.3 km; 74.2 to 98.4 mi)[99] for the Harpoon missile system, these two missile systems displaced the 16-inch guns and their maximum range of 42,345 yards (38.7 km; 20.9 nmi)[35] to become the longest-ranged weapons on the battleships during the 1980s. "B" was the smallest at 52,707 long tons (53,553 t) standard; like "A" it had a top speed of 32.5 knots, but "B" only required 225,000 shp (168,000 kW) to make this speed. The Soviet Navy was commissioning the Kirov class of missile cruisers, the largest type of surface warship built since World War II (other than aircraft carriers or amphibious assault vessels). [80] There were a number of proposals in the early Cold War to convert the class to take into account changes in technology and doctrine. [53], USS North Carolina (BB-55) was laid down on 27 October 1937, the first battleship begun by the United States since the never-completed South Dakota class of the early 1920s. They had a main armored belt that was 12-inch (305 mm) thick amidships, inclined at 15°, and backed by 0.75-inch (19 mm) Special Treatment Steel (STS). In the end, none of these proposed conversions for the battleships were ever authorized. However, it was found that a purpose-built helicopter carrier would be more economical, so the plans were shelved. [151] In 1958, the engines installed on Kentucky were salvaged and installed on the Sacramento-class fast combat support ships Sacramento and Camden. Although North Carolina could steam at 24 knots (44 km/h; 28 mph) soon after the explosion, she was later forced to slow to 18 knots (33 km/h; 21 mph) to ensure that temporary shoring did not fail. When the New Jersey was reactivated in 1968 for the Vietnam War, she was outfitted with the ULQ-6 ECM system. Washington retained its six 1.1 in quads until the middle of 1943, when ten quad 40 mm guns replaced them. But the war would be entirely different than what the Navy envisioned. [20] The Second Vinson Act updated the provisions of the Vinson-Trammell Act of 1934 and the Naval Act of 1936, which had "authorized the construction of the first American battleships in 17 years", based on the provisions of the London Naval Treaty of 1930;[19] this act was quickly signed by President Franklin D. Roosevelt and provided the funding to build the Iowa class. Instead, the company was awarded two destroyer tenders in December 1937, Dixie and Prairie. Even during the development process of the preceding North Carolina-class and South Dakota-class battleships, designs that could achieve over 30 knots in order to counter the threat of fast "big gun" ships were seriously considered. [44], Both North Carolina and Washington, designed prior to radar, were originally fitted with many fire-control and navigational optical range-finders. Once there, she received a full overhaul, along with a new bow; this work lasted from March until April. By the time the Iowas were completed and commissioned in 1943–44, the considerable increase in anti-aircraft armament – along with their associated splinter protection and crew accommodations – and additional electronics had increased standard displacement to some 47,825 long tons (48,592 t), while full load displacement became 57,540 long tons (58,460 t). Reproduced in Muir, "Gun Calibers and Battle Zones," 26. As part of Operation "Magic Carpet", soldiers were embarked to be returned to the United States. The turbines that had already been installed could not fully take advantage of the higher pressure and temperature steam, and so the level of efficiency was not as high as it should have been. The first plans made for this indicated that 30 knots (56 km/h; 35 mph) was possible on a standard displacement of about 37,600 long tons (38,200 t). Ten men, six from Washington, were killed or listed as missing. [66], In addition to these search and navigational radars, the Iowa class were also outfitted with a variety of fire control systems for their gun systems, and later for their missile systems. [64][66][67], Washington left the North Sea bound for the United States on 14 July with an escort of four destroyers; upon arrival at the New York Naval Yard on the 23rd, she was given a full overhaul which took a month to be completed. Iowa, New Jersey, and Missouri were equipped with the Block 0 version of the Phalanx, while Wisconsin received the first operational Block 1 version in 1988. Although all were officially stricken from the Naval Vessel Register they were spared scrapping and were donated for use as museum ships. It was 223.8 inches (5,680 mm) long overall, had a bore length of 190 inches (4,800 mm) and a rifling length of 157.2 inches (3,990 mm). [41], When firing the same shell, the 16-inch/45 Mark 6 had a slight advantage over the 16-inch/50 Mark 7 when hitting deck armor—a shell from a 45 cal gun would be slower, meaning that it would have a steeper trajectory as it descended. "A" was the only one to remain within the 35,000–tons displacement limit set in the Washington Naval Treaty and reaffirmed in the Second London Naval Treaty. A final two, "L" and "M," would use quadruple turrets to save weight (similar to the French Dunkerque) while still mounting 12 guns. As the bureaus were independent of one another, they did not realize that the two plans could not go together until November 1938, when the contract design was in the final stages of refinement. When the Bureau of Ordnance introduced a "super-heavy" 16-inch shell, the ships were redesigned ("A1", "B1" and "C1") in an attempt to provide protection against it, but this introduced severe weight problems: "A1" was only 500 long tons (510 t) below the 35,000-ton limit, while the other two were close to 40,000 long tons (41,000 t). Although the changes meant extra weight and increasing the beam by 1 foot (0.30 m) to 108 feet 2 inches (32.97 m), this was no longer a major issue; Britain and France had renounced the Second London Naval Treaty soon after the beginning of the Second World War. The other two, the New York Naval Shipyard and Philadelphia Naval Shipyard, were run by the government. The 20 mm weapons were also reduced at some point so that both ships were decommissioned with sixteen t… New Jersey completed fitting out and trained her initial crew in the Western Atlantic and Caribbean before transferring to the Pacific Theatre in advance of the planned assault on the Marshall Islands, where she screened the U.S. fleet of aircraft carriers from enemy air raids. The conclusions were seen as a vindication by some who believed that too much had been sacrificed in the design of the North Carolinas—the torpedo defense system had come close to breaking near one of the most important areas of the ship (a magazine), after all—and the General Board called for the fifth and sixth Iowa-class battleships, Illinois and Kentucky, to have a torpedo bulge added outside their magazines. Although she dodged one torpedo on 6 September, she was not able to avoid another on the 15th. [51][52], Construction of the North Carolina class was slowed by the aforementioned material issues, the changes made to the basic design after this date—namely the substitution of 16-inch for 14-inch guns—and the need to add both length and strength to the slipways already present in the navy yards. [19], At least 35 different final designs were proposed. All of the urinals and all but one of the toilets on the Iowa class flush with saltwater in order to conserve fresh water. In 1952, AN/SPS-10 surface-search radar and AN/SPS-6 air-search radar replaced the SK and SG radar systems, respectively. The transverse bulkhead armor on Missouri and Wisconsin was increased to 14.5 inches (368 mm); this extra armor provided protection from fire directly ahead, which was considered more likely given the high speed of the Iowas. At 35,000 yards (20 mi; 32 km), a shell from a 45 cal would strike a ship at an angle of 45.2 degrees, as opposed to 36 degrees with the 50 cal. This was confirmed by Roosevelt, as the private shipyards' bids were seen as unjustly inflated. For comparative purposes, the boilers fitted to the most recently designed heavy cruisers provided steam at 300 psi (2,100 kPa) and 572 °F (300 °C). The weight gained from reducing the speed was added back in firepower and protection: "VII" would have had twelve 14-inch/50 caliber guns in four triple turrets and an immune zone against its own 14-inch gun between 21,400 and 30,000 yd (11 and 15 nmi; 20 and 27 km). She also moved in to hit Kwajalein with her guns on 30 January. Consequently, the AA guns and their associated fire-control systems were removed when reactivated. It posed questions to the Naval War College, asking for their opinion as to whether the new class should be a "conventional" 23-knot (43 km/h; 26 mph) ship with an eight-nine, 16-inch main battery, or rather one akin to "A", "B" or "C". [63] The Iowas were outfitted with four screws: the outboard pair consisting of four-bladed propellers 18.25 ft (5.56 m) in diameter and inboard pair consisting of five-bladed propellers 17 ft (5.18 m) in diameter. Departing in late November, Washington first steamed to Makin to provide protection for ships there, then Ocean Island to prepare to bombard Nauru with her sister North Carolina, all four South Dakota-class battleships, and the carriers Bunker Hill and Monterey. About 43 feet (13 m) protrudes from the gun house. The outer hull was intended to detonate a torpedo, with the outer two compartments absorbing the shock and with any splinters or debris being stopped by the lower armored belt and the empty compartment behind it. Shortly after this announcement, Roosevelt was bombarded with heavy lobbying from citizens and politicians from Camden and the state of New Jersey, in an ultimately futile attempt to have the construction of North Carolina shifted to Camden's New York Shipbuilding; such a contract would keep many men employed in that area. [54][57][58][59], Repaired and refitted at the facilities in Pearl Harbor, North Carolina operated as a carrier escort for Enterprise and Saratoga for the remainder of 1942 and the majority of 1943 while they provided cover for supply and troop movements in the Solomons. 2020-12-25 13:50:09 23 hours ago; Views 0; By:Battleship New Jersey; A + A-0. [43], On both ships, two more quadruple sets of 1.1 in guns were added in place of two searchlights amidships. The obsolete electronics and anti-aircraft armament were removed to make room for more modern systems. Charles Myers, a former Navy test pilot turned Pentagon consultant, proposed replacing the turret with vertical launch systems for missiles and a flight deck for Marine helicopters. Two semi-balanced rudders gave the ships a tactical turning diameter of 814 yards (744 m) at 30 kn (56 km/h; 35 mph) and 760 yards (695 m) at 20 kn (37 km/h; 23 mph). [47][48], The 5-inch/38 gun would remain on the battleships for the ships' entire service life; however, the total number of guns and gun mounts was reduced from twenty guns in ten mounts to twelve guns in six mounts during the 1980s' modernization of the four Iowas. [84], In 1954, the Long Range Objectives Group of the United States Navy suggested converting the Iowa-class ships to BBGs. [84][19] A similar conversion had already been performed on the battleship Mississippi (BB-41/AG-128) to test the RIM-2 Terrier missile after World War II. The Montana was basically a larger Iowa Class Battleship. With repairs completed, the battleship joined with Enterprise on 6 June for assaults within the Marianas; as part of these, North Carolina used its main battery to bombard Saipan and Tanapag. It was reportedly favored by President Franklin Delano Roosevelt, but as aircraft launched from catapults were necessarily inferior to most carrier- or land-based aircraft because of the floats used to land, nothing came of the design. Inter-war modernization … [34][35] The guns are housed in three 3-gun turrets: two forward of battleship's superstructure and one aft, in a configuration known as "2-A-1". [116][N 12], The Iowa class became culturally symbolic in the United States in many different ways, to the point where certain elements of the American public – such as the United States Naval Fire Support Association – were unwilling to part with the battleships, despite their apparent obsolescence in the face of modern naval combat doctrine that places great emphasis on air supremacy and missile firepower. However, the General Board finally decided to use faster ships, which "G" and "H" were not. [149], Wisconsin was ordered 12 June 1940, laid down 25 January 1942, launched 7 December 1943, and commissioned 16 April 1944. By September, Washington had twenty more 20 mm guns added, for a total of forty, but five were removed—along with all of the .50 caliber guns—shortly thereafter when two quadruple sets of 1.1 in guns were added. [36], In World War II, the electronic countermeasures (ECM) included the SPT-1 and SPT-4 equipment; passive electronic support measures (ESM) were a pair of DBM radar direction finders and three intercept receiving antennas, while the active components were the TDY-1 jammers located on the sides of the fire control tower. The problem was particularly acute near the aft main battery director, which required additional reinforcing braces due to the vibrations. [54][60], Joining Task Force 58 in January 1944, North Carolina escorted aircraft carriers as the flagship of Vice Admiral Willis A. Lee, Commander, Battleships, Pacific Fleet (ComBatPac) for much of the year, providing support for airborne strikes on Kwajalein, Namur, Truk (twice), Saipan, Tinian, Guam, Palau, Woleai, and Hollandia in January–April. [111], The debate over battleships in the modern navy continued until 2006, when the two reinstated battleships were stricken after naval officials submitted a two-part plan that called for the near-term goal of increasing the range of the guns in use on the Arleigh Burke-class destroyers with new Extended Range Guided Munition (ERGM) ammunition intended to allow a 5-inch projectile fired from these guns to travel an estimated 40 nautical miles (74 km; 46 mi) inland. Battleship Shootout: KM Bismarck vs. USS Iowa vs. IJN Yamato vs. HMS King George V September 28, 2012 in General Topics The battleship , moreso than any kind of warship–excepting perhaps the man O’ war –was often the visual representation of a country’s military might. [15][B], Although these original three studies were all fast battleships, the General Board was not definitively committed to the higher maximum speeds. In addition to these upgrades, 8,600 long tons (8,700 t) of additional fuel oil was also suggested to serve in part as ballast for the battleships and for use in refueling destroyers and cruisers. The 1919–1920 General Board proposals planned for slightly smaller, but still significant, acquisitions beyond the 1916 plan: two battleships and a battlecruiser for the fiscal year 1921, and three battleships, a battlecruiser, four aircraft carriers and thirty destroyers between the fiscal years 1922 and 1924. The four Iowa-class ships were the last battleships commissioned in the US Navy. [30], Admiral Reeves also came out strongly in favor of the larger weapon. The North Carolina had a thick steel deck, as did the bismark, the wood casing over it was more for traction than anyhting else. Upon determination the result would cost more and be less capable than building from scratch construction resumed, but was canceled for good approximately one-quarter complete on 11 August 1945. [18], Many officers in the United States Navy supported the construction of three or four battlecruiser-type ships for carrier escorts and to counter Japan's Kongō class. After the end of the First World War, several navies continued and expanded naval construction programs that they had started during the conflict. The ends of the armored citadel are closed by 11.3-inch (287 mm) vertical Class A transverse bulkheads for Iowa and New Jersey. [11], With the staggering costs associated with such programs, the United States' Secretary of State Charles Evans Hughes invited delegations from the major maritime powers—France, Italy, Japan, and the United Kingdom—to come together in Washington, D.C. to discuss, and hopefully end, the naval arms race. Missouri and Wisconsin both used the Pioneer UAVs successfully during Operation Desert Storm, and in one particularly memorable incident,[105] a Pioneer UAV operated by Wisconsin received the surrender of Iraqi troops during combat operations. During Operation Desert Storm in 1991, Missouri and Wisconsin fired missiles and 16-inch (406 mm) guns at Iraqi targets. During the 1980s these battleships made use of the RQ-2 Pioneer, an unmanned aerial vehicle employed in spotting for the guns. [158] The interruption lasted for two and a half years while a parallel aircraft carrier debate played out as with Illinois, reaching the same conclusion. Also in April, North Carolina destroyed defensive installations on Ponape before setting course for Pearl Harbor for repairs to a damaged rudder. These treaties heavily influenced the design of the North Carolina class, as can be attested to in the long quest to find a ship that incorporated everything considered necessary while remaining under 35,000 long tons. Four ships: Iowa, New Jersey, Missouri, and Wisconsin were built. At the height of Navy Secretary John F. Lehman's 600-ship Navy plan, nearly 600 ships of all types were active within the Navy. Nevertheless, skegs would be improved and incorporated in the designs of all subsequent American battleships, with vibration problems largely eliminated on the Iowa class battleships. The Iowa-class battleships were designed in 1938 when the Navy proposed a new class of battleships that were to develop on the lessons learned from the development and construction of the North Carolina-class and South Dakota-class of battleships. [152] Ultimately, what remained of the hulk was sold for scrap on 31 October 1958. In these areas, the fifth compartment was deleted; instead, there was an outer empty compartment and two liquid-filled spaces, backed by another empty compartment. On 4 June, Washington hosted the commander of naval forces in Europe, Admiral Harold Rainsford Stark, who set up a temporary headquarters on the ship for the next few days. After trials and initial training in Chesapeake Bay, she transferred to the Pacific Fleet in 1944, and was assigned to protect the US fleet of aircraft carriers involved in operations in the Philippines until summoned to Iwo Jima to bombard the island in advance of the Marine landings. The roof was 7 inches (178 mm) thick and the bottom was 3.9 inches (99 mm) thick. [112][113] The long-term goal called for the replacement of the two battleships with 32 vessels of the Zumwalt class of guided-missile destroyers. The increases in weight also reduced the ships' cruising range. This testing required her to be at sea, and the many resulting trips out of New York Harbor to the Atlantic Ocean caused her to be nicknamed "The Showboat". [31], The Iowas exhibit good stability, making them steady gun platforms. New Jersey was ordered 4 July 1939, laid down 16 September 1940, launched 7 December 1942, and commissioned 23 May 1943. [139] The ship later escorted U.S. aircraft carriers conducting air raids in the Marianas campaign, and then was present at the Battle of Leyte Gulf. [81][82] Ultimately, nothing came of the design proposal to rebuild these two ships as aircraft carriers and they were cleared for construction as fast battleships to conform to the Iowa-class design, though they differed from the earlier four that were built. [54], North Carolina then joined the carrier Saratoga's screen, and protected her while support was rendered to American troops fighting on Guadalcanal. Along with this came the associated weight in supporting these new strains: the structure of the ship had to be reinforced and the power plant enlarged to avoid a drop in speed.
