Aircraft Carrier Preliminary Design Drawings

Nine of the 211 design drawings in the 1911-1925 "Spring Styles" Book treat Aircraft Carriers. Two images reproduced here depict hand-written notes on small pieces of paper attached to one of the drawings, identifying changes to be made following design discussions. Of the nine individual aircraft carrier ship designs included here, five represent preliminary designs developed to illustrate the potential for new construction of a large, purpose-built ship created prior to the limits imposed by the Washington Treaty on naval arms limitation enacted in 1922. The other four ship designs all reflect the impact of the treaty. One illustrates the design adopted for the conversion of two uncompleted battle cruisers into aircraft carriers (becoming Lexington (CV-2) and Saratoga (CV-3).) Three others illustrate design possibilities available under the terms of the treaty, one toward the upper end of size and two near the lower limit considered potentially feasible for construction of a useful ship. No ships were built to any of these last three preliminary design concepts.

This page features those 1911-1925 Bureau of Ships "Spring Styles" plans that concern aircraft carriers.

    The Aircraft Carrier drawings included in this album are:

    --Five design proposals for a new, purpose-built large aircraft carrier:

  • S-584-167: Preliminary Study # 2 - Air Craft Carrier - 32-3/4 knot - November 17, 1920. Preliminary design drawing of a 35,000 ton ship with a main battery of sixteen 6-inch guns and a maximum speed of 32.75 knots. This plan envisaged the construction of a large aircraft carrier from the keel up, but following the Washington Treaty on naval arms limitation in 1922 two battle cruisers under construction were instead converted to large aircraft carriers.
  • S-584-168: Preliminary Study # 3 - Air Craft Carrier - 34-3/4 knot - November 17, 1920. Preliminary design drawing of a 34,500 ton ship with a main battery of sixteen 6-inch guns and a maximum speed of 34.75 knots. This plan envisaged the construction of a large aircraft carrier from the keel up, but following the Washington Treaty on naval arms limitation in 1922 two battle cruisers under construction were instead converted to large aircraft carriers.
  • S-584-169: Preliminary Study # 1 - Air Craft Carrier - 29 1/2 knot - November 26, 1920. Preliminary design drawing of a 25,500 ton ship with a main battery of sixteen 6-inch guns and a maximum speed of 29.5 knots. This plan envisaged the construction of a large aircraft carrier from the keel up, but following the Washington Treaty on naval arms limitation in 1922 two battle cruisers under construction were instead converted to large aircraft carriers.
  • S-584-179: Aircraft Carrier 1922 - Scheme "B" - May 5, 1921. Preliminary design drawing of a 39,000 ton ship with a main battery of sixteen 6-inch guns and a maximum speed of 34 knots. This plan envisaged the construction of a large aircraft carrier from the keel up, but following the Washington Treaty on naval arms limitation in 1922 two battle cruisers under construction were instead converted to large aircraft carriers.
  • S-584-179-A: Paper note attached to Bureau of Construction and Repair Plan No.006217, Aircraft Carrier 1922 Scheme "B"; (see Photo # S-584-180.) This note records instructions given to the draughtsman in making changes to the plan ("Scheme B" of May 5, 1921) following a meeting with senior Navy officials.
  • S-584-179-B: Paper note attached to Bureau of Construction and Repair Plan No.006217, Aircraft Carrier 1922 Scheme "B"; (see Photo # S-584-180.) This note records additional instructions given to the draughtsman in making changes to the plan ("Scheme B" of May 5, 1921) following a meeting with senior Navy officials.
  • S-584-180: Aircraft Carrier (1922) No. # 2 - September 9, 1921. Preliminary design drawing of a 39,000 ton ship with a main battery of six 6-inch guns and a maximum speed of 34 knots. This plan envisaged the construction of a large aircraft carrier from the keel up, but following the Washington Treaty on naval arms limitation in 1922 two battle cruisers under construction were instead converted to large aircraft carriers.

    --The design selected for conversion of two Lexington class Battle Cruisers to Aircraft Carriers, which became aircraft carriers Lexington and Saratoga:

  • S-584-182: U.S. AirPlane Carriers No. 1 & 2 - Battle Cruisers Converted - February 18, 1922. Preliminary design drawing of a 38,830 ton ship with a main battery of eight 8-inch guns and a maximum speed of 34 knots. This drawing depicted the expected features of aircraft carriers that could be built using hulls already begun as battle cruisers of the "Lexington" (Battle Cruiser # 1) class. The Lexington (CV-2) and Saratoga (CV-3) were completed to this design.

    --Three design proposals for new Aircraft Carriers to be built under Treaty design constraints, none constructed:

  • S-584-183: Air Plane Carrier - Protected - February 18, 1923. Drawing from Preliminary Design Book No.282 of a ship of 29,250 tons with a main battery of nine 8-inch guns and a maximum speed of 27 knots. This drawing provided an example of a design that might be built within the tonnage available to the United States for aircraft carriers under the 1922 Washington Treaty on naval arms limitation. No ship of this type was built.
  • S-584-184: 13,000 Ton Air Plane Carrier - April 23, 1923. Drawing from Preliminary Design Book No.286 of a ship of 13,000 tons with a main battery of six 8-inch guns and a maximum speed of 28 knots. This drawing provided an example of a design that might be built within the tonnage available to the United States for aircraft carriers under the 1922 Washington Treaty on naval arms limitation. No ship of this type was built.
  • S-584-201: 10,000 Ton Treaty Displacement Airplane Carrier - January 15, 1925. Preliminary design drawing of a 10,000 ton ship with a main battery of four 6-inch guns and a maximum speed of 30 knots. This drawing provided an example of a design that might be built within the tonnage available to the United States for aircraft carriers under the 1922 Washington Treaty on naval arms limitation. No ship of this type was built.
