Junkers (OKB-1) EF140
Twin engine Jet bomber of 1948, built in Russia
Junkers EF140-V1 of 1948
The lack of adequate Jet engines forced Baade to continue a six engine layout on the Junkers EF131 in 1946. When more powerfull Russian engines became available in 1948 the EF131 Tests were stopped and the EF131 was reequipped with two 3300 kp Mikulin AM-TRKD-01 engines under the Designator Junkers EF140. The EF140 also got new wings with a new Profile. The first flight of the Junkers EF140-V1 was performed by Paul Jügle on 30th September 1948 at Tjopljstan in Russia.
The Mikulin engines were not reliable. Most flights had to be aborted due to engine fire. Therefore the engines were changed to two 2700kp WK-I engines. For an improved range also tip tanks were added to the wings. On 12th October 1949 the redesigned Junkers EF140R reconaissance aircraft flew for the first time.

Based on the Junkers EF140R a further improved Junkers EF140B/R was under construction in 1950, when Baade was advised to stop any further work on the EF140 Project. In June 1950 any activities on the EF140 Programme were stopped and both aircraft were later scrapped.
