Signal Corps Dirigible No. 1 was the first powered aircraft ordered for the Signal Corps by the Aeronautical Division of the United States Army. The purchase of SC-1, a dirigible designed by Thomas Scott Baldwin was the result of urgings by Chief Signal Officer Brigadier General James Allen. After seeing Baldwin demonstrate a dirigible at the St. Louis air meet in 1907, Allen had urged the U.S. Army to buy a dirigible as many European armies had dirigibles by the turn of the century.
On 5 August 1908, the Army tested SC-1 at Fort Myer, Virginia. The craft fell short of a 2 hour, 20 mph objective to meet a $8,000 per unit award. The Army formally accepted the craft as Signal Corps Dirigible No. 1 paying $5,737.50. On 28 Aug. 1908 Lieutenants Frank Lahm, Thomas Selfridge and Benjamin Foulois were taught to fly the craft.
On 26 May, pilot Lieutenant Lahm and Lieutenant Foulois made a flight in SC-1 at Fort Omaha and manoeuvred the craft at will. SC-1 remained there until scrapped in 1912. The Army did not purchase another dirigible until after World War I.
