In following out this ambition, we placed contracts for the production of 10,000 Hispano-Suiza 300-horsepower engines. Of these, 5,000 were to be built by the Wright-Martin Aircraft Corporation. To enable this company to fulfill the new contract we leased to it the plant owned by the Government in Long Island City which had formerly been owned by the General Vehicle Co. The other 5,000 of these engines were to be built by the Pierce-Arrow Motor Car Co. at Buffalo. We also contracted for the entire manufacturing facilities of the H. H. Franklin Co., of Syracuse, N. Y., to aid both the Wright-Martin Corporation and the Pierce-Arrow Co., in this contract. The first of these high-powered Hispano-Suiza engines were expected to be delivered in January, 1919, but this project, of course, was interrupted by the armistice.

To summarize the complete engine program of the aviation development, the total contracts for engines provided for the delivery of 100,993 engines. These were divided as follows:

OX9,450
A7A2,250
Gnome342
Le Rhone3,900
Lawrence451
Hispano-Suiza: 180-horsepower4,500
Hispano-Suiza: 150-horsepower4,000
Hispano-Suiza: 300-horsepower10,000
Bugatti2,000
Liberty-1256,100
Liberty-88,000

The delivery of aviation engines of all types to the United States Government, engines produced as part of our war program, were as follows, by months:

July, 191766
August, 1917139
September, 1917190
October, 1917276
November, 1917638

The production by types was as follows to November 29, 1918:

OX8,458
Hispano-Suiza4,100
Le Rhone1,298
Lawrence451
Gnome280
A7A2,250
Bugatti11

At the signing of the armistice the United States had produced about one-third of the engines projected in its complete aviation program.

Of the output of training engines to November 29, 1918, the various airplane plants took 9,069 for installation in planes, 325 (all of these being Le Rhone rotaries) went to the American Expeditionary Forces in France, 515 (all of which were Hispano-Suizas) were taken by the Navy, a single A7A model was sent to one of the allied countries, while 6,376 engines were sent directly to the training fields.
