Project history

This wooden boat was developed in 1917 for emergency production. The Elco Company already had built large numbers of 80ft motor launches for the Royal Navy, but the General Board considered them too small for sufficient sea-keeping. Wood was used for speed of construction; it was hoped that the entire US order of 345 craft could be ready by 1 January 1918. France was assigned 50 more, and then another 50 to bring the programme up to 448 units. Although they were not delivered on time, the sub-chaser programme was considered one of the triumphs of US World War One mobilisation.

At first it appeared that powerplants would be a bottleneck, and the Navy considered both requisitioning private motor boats and buying the Elco 80-footers. However, three standard heavy-duty gasoline engines (220bhp each) were substituted for the proposed pair of 300bhp units, and the emergency procurement plans were abandoned.

A prominent small-craft designer, Loring Swasey, was retained to design them; he was also responsible for the World War Two SC. The design was approved late in March 1917; by May, the General Board was complaining that so small a boat could not suffice to deal with submarines in the open ocean, and that a much larger steel-hulled type was needed. The latter became the Eagle Boat.

Modernizations

None.

1/1946, all survived: 1 x 1 - 76/23 Mk 14 or 1 x 1 - 76/24 Mk 15, 2 x 1 - 7.6/90, 1 DCT

Naval service

In 1919 SC413, 414, 233, 234, 267, 275, 276, 279 - 281 and 307 were transferred to Army (first 2 before completion).

Many chasers were transferred in 1919-1920 to Coast Guard (they were named). SC408, 409, 411, 417 - 423, 435, 436, 438 were never commissioned by Navy.
