Notes: After contracting for a total of thirty Design 1013 cargo ships between May 1917 and April 1918, all of which it delivered, the Los Angeles Shipbuilding & Drydock Co. received a contract for ten more on 23 August 1918. Following the end of the war these ten were suspended on 25 January 1919 although a large percentage of the materials for them was alreay on hand at the yard. With the cessation of hostilities and the slowing of the USSB's building program, the EFC began to consider building larger vessels (see Design 1117). In an effort to use the materials on hand and at the same time obtain an increased deadweight capacity, the shipbuilder prepared a modified design which was a development of the 8800-ton vessel and submitted it to the USSB for approval. In the modified design the same lines were used as for the 8800-ton ships, with the addition of 20.25' in the length of the midship body, making the length between perpendiculars 430.4' instead of 410.1'. The forecastle, bridge, and poop decks were made continuous over the entire length, producing a vessel with a flush upper deck and two 'tween decks for a total of three decks (upper, second, and third) in the hull, the upper deck being the strength deck. The scantlings for the modified design were worked out in accordance with ABS rules, and by making the upper deck the strength deck and relocating the other materials it was found possible within the rules of the American Bureau of Shipping to utilize the steel which was already on hand for the 8800-ton ships. The ships were thus full scantling instead of shelter deck type ships. In the modified design about 600 tons more steel were required than for the 8800-ton vessels with an increase in carrying capacity of about 2700 tons. Instead of the two masts serving four hatches and two small derrick posts serving a small fifth hatch in Design 1013, the new design had seven pairs of tall derrick posts or kingposts serving six large hatches. The foremost and aftermost pairs of derrick posts were connected at the top by a lattice bridge, on which topmasts were stepped to carry the wireless antennae, halyards, etc. Hold pillars were located at hatch corners only, making the five cargo holds particularly spacious and free from obstructions. For propulsion the shipyard gave the new ships the same 3500 ihp reciprocating engine of its own design that it had fitted to 22 of its Design 1013 ships. This engine was generously proportioned, having developed over 4000 ihp on the loaded sea trials of some of the 8800-ton ships, and was expected to produce the same designed speed in the new ships although they were to carry 2700 additional tons. On 19 September 1919 the last five of the ten suspended ships (EFC Hulls 2248 and 2357-2360) were cancelled and the earlier five (EFC Hulls 2243-2247) were reinstated with their deadweight tonnage increased to 11,000 tons. According to a magazine report on the launch of the third of these large ships, West Greylock, "The particular point of interest to the shipping men apart from the good speed and economy in fuel shown by this type of freighter lay in their provision and admirable arrangement of hatchways and cargo handling appliances. The design for the vessel was worked out at the plant of the builders folowing suggestions made by practical shipping men who had found that the docks of most ports were seldom provided with sufficient cargo handling machinery, consequently causing considerable delay and loss of time in unloading the cargo of a freighter. It was particularly to obviate this trouble that deck derricks were provided in quantity and capacity sufficient to assure rapid discharging of cargo, thus making the ship practically independent of the cargo-handling equipment of the ports at which she might call. While in San Francisco recently, the West Lewark ... found it possible to employ at the same time nine separate gangs of stevedores." The magazine had previously commented that "this class of freighter marked the biggest advance in cargo carrying ships made by any shipyard in the United States in the past four years." However the glut of war-built ships and the postwar depression in the shipping market helped limit the further development of this type.

S.S. West Greylock (EFC Design 1133, EFC Hull 2245) on her trial trip on 25 August 1921. This ship was built by the Los Angeles Shipbuilding & Dry Dock Co., where in September 1919 the last ten ships of Design 1013 were cancelled and replaced by five ships of this larger design.
