E-class blimp

The E-class was a single United States Navy training blimp, the E-1, built by Goodyear during the First World War as one of a group of three small blimps offered to the government. Two were bought by the Navy, as E-1 and F-1, and one by the Army, as A-1. All three had identical envelopes but different cars. The E-1 was delivered to Pensacola, Florida, in December 1918 and flown only there, serving as a trainer at the Airship School. It received a new envelope in December 1920 and was retired from service sometime in 1924. It was 162 feet long, carried a crew of three, was driven by one Thomas-Morse engine and had a top speed of 56 miles per hour.
