RDS-5 (Реактивный двигатель специальный Reaktivnyi Dvigatel Specialnyi; Special Jet Engine) was a plutonium based Soviet atomic bomb, probably using a hollow core ( полой конструкции poloy konstruktsii; hollow construction [1]). Two versions were made. The first version used 2kg Pu-239 and was expected to yield 9.2 kilotons. The second version used only 0.8kg Pu-239 [1][2].

The two versions of the RDS-5 were tested during a series of 3 tests on September 3, 8 and 10 1953 in the Semipalatinsk test site. The test on September 3 (Joe 6 [3]) was probably of the 2kg version and achieved a yield of 5.8 kiloton (compared to the expected 9.2 kiloton). The test on September 8 was probably of the 0.8kg version and yielded 1.6 kiloton[1][2].
