FY 1942 (all but ATR-90, ex BAT-2, FY 1941). As follow-ons to the BAT-1 class (q.v.) the British submitted Lend-Lease Requisition BAD-1001-9 for nine more tugs (designated ATR 41-49 by the U.S.), followed by Requisition BAD-1750 for six "143-foot ocean-going salvage tugs" (ATR 91-96). By this time ships for the British and for the U.S. were being pooled in a single U.S. building program and were then being allocated between the two countries by the Munitions Assignment Board according to need as of the time of their completion. On 17 Jan 42 CNO directed the construction of ATR 41-49 as part of the U.S. Navy's Maximum War Effort (1799 Vessel) Program, and on 18 Jan 43 VCNO directed the construction of ATR 91-100 (four more than the British had requisitioned) using tonnage still available in this program.
Of the 29 steel rescue tugs that they had requisitioned the British ultimately received 23, including all but one of the BAT's. On 30 Sep 42 the Munitions Assignment Board allocated ATR 43 to the U.S., and it probably allocated BAT-2 (listed here as ATR-90) to the United States in the same action. At around the same time the British received ATR 41-42 and the last two of the BAT's. By early 1943 the competition between the British and the U.S. for tug allocations had become intense, because both countries had urgent requests for tugs from commanders all over the world (VCNO estimated that there was an urgent need for nearly 100 seagoing tugs as of March 1943, a number that could not possibly be met) and because the tug building program had been set back when the huge landing craft program for the proposed 1943 invasion of Europe from the U.K. was put into effect with over-riding priority. By May 1943 ATR 44-47 had been allocated to the U.S., with the British receiving in exchange four American wooden rescue tugs (ATR 17-20) under Requisition BAD 1400/9. The British later received ATR 91-96 as planned but asked for and received no additional American ATR's, either steel or wood. As with the 14 BAT's, the Bureau of Ships contracted with the General Motors Corporation to build ATR 41-49 and 91-100, with G.M. providing the diesel engines and subcontractors building the hulls.
On 16 Apr 43 the Under Secretary of the Navy directed the construction of the next batch of ATRs for the U.S. Navy, ATR 101-140. The U.S. had initially intended to fill its own needs for rescue tugs with the wooden ATR-1 type (q.v.) and the new ships were to have been of this type, but in early 1943 the Americans began to feel that the steel ATR's were more suitable for the Pacific, partly because the wooden tugs might deteriorate rapidly from attacks by tropical shipworms. On 13 May 43 BuShips formally recommended that ATR 101-140, be changed from wood to steel construction, and CNO approved this recommendation on 3 Jun 43. As all of these ships had been reclassified as Auxiliary Ocean Tugs (ATA) prior to completion, they are listed here as the first installment of the ATA-174 class, although they were identical in design to both the ATR-41 class and the preceding BAT-1 class.
The same design was used for 18 sisters built for the Army at the Levingston shipyard. These followed ATR 91-96 on the building ways and preceded ATA 174-198. First came LT 454-456, under a contract of 18 Mar 43 with Levingston SB and fitted with Cooper Bessemer Model GSB diesels (750 HP). These vessels were accepted between Dec. 1943 and Mar. 1944. They were followed by LT 528-538 and 578-581 under a contract of 26 Apr 43 with General Motors, Levingston being the sub-contractor for the hulls, and were fitted with G.M. Cleveland Model 12-278A or 12-950-750 diesels (950 HP). These vessels were accepted between Jan. 1944 and June 1944. The Army nomenclature for Design 377 was "Tug, Ocean-Going, Diesel-Electric, Steel, 143'. The original version of Design 377 (LT 454-456) was undated and new specs were issued in July 1943. The original specifications for Design 377A (the others) were dated 3 Apr 42 and they were amended on 11 May 43; Specifications for a Design 377AS were issued on 15 Apr 44 but apparently not used. The dimensions of all as recorded by the Army were 143.0' oa x 33.0' molded.
The Argentine YAMANA must have been one of these Army ships as no Navy 143-foot candidate (BAT, ATR, or ATA) is available. The Argentines recorded her as "ex ATA-126," but the correct designation, AT-126, was long out of use by the time the Argentines acquired the ship in 1948 and both this ship (as ATR-48) and ATA-146, also sometimes associated with YAMANA, are well documented as having become Moran tugs. The fates of the Army 143' tugs LT-454, 529, 531, and 578-80, on the other hand, are currently unknown. YAMANA was added to the Argentine Navy List on 7 Feb 48, departed Terminal Island, Calif., on 15 May 48 escorting 5 former LCI's (BDI 5-9) to Argentina, and was stricken in 1984. Of the other Army tugs, LT-532 joined the Navy as ATA-239 and LT-455 became ATA-240 after the war.
