The FASTA-4 was developed in 1979 by the Volksmarine (East German Navy) as a mean of AA close-defense for its ships. It is basically a quad-Strela-2 launcher, but was later improved to fire Strela-3 in its FASTA-4M variant. That same year, the VM motorized the FASTA by mounting it on LO-1800 truck to provide naval bases with cheap and mobile AA defense.
