According to the Kazakhstani Atomic Energy Agency, a 0.3 kT surface nuclear explosion was conducted on 2 February 1956.  Other sources indicate that a missile test took place at Aralsk on the same date.  Yet another source confirms the surface nuclear explosion on 2 February 1956 and reports an underwater nuclear explosion at Aralsk one year earlier, in February 1955.  Jane's Intelligence Review has also identified Aralsk as a biological and chemical weapons test site.
