- Kaliningrad K-5
The Kaliningrad K-5 (
NATO reporting name AA-1 "Alkali"), also known as RS-1U or product ShM, was an earlySoviet air-to-air missile .History
The development of the K-5 began in 1951. The first test firings were in 1955. It was tested (but not operationally carried) by the
Yakovlev Yak-25 . The weapon entered service as the Grushin/Tomashevich ( _ru. Грушин/Томашевич) RS-2U (also known as the R-5MS or K-5MS) in 1957. The initial version was matched to the RP-2U (Izumrud-2) radar used on the MiG-17PFU,MiG-19 PM. An improved variant, K-5M or RS-2US in PVO service, entered production in 1959, matched to the RP-9/RP-9U (Sapfir) radar of theSukhoi Su-9 . ThePeople's Republic of China developed a copy under the designation PL-1, for use by their J-6B fighters.The difficulties associated with beam-riding guidance, particularly in a single-seat
fighter aircraft , were substantial, making the 'Alkali' primarily a short-range anti-bomber missile. Around 1967 the K-5 was replaced by the K-55 (R-55 in service), which replaced the beam-riding seeker with thesemi-active radar homing orinfrared seeker s of the K-13 (AA-2 'Atoll'). The weapon was 7.8 kg (17.2 lb) heavier than the K-5, but had a smaller 9.1 kg (20.1 lb) warhead. The K-55 remained in service through about 1977, probably being retired with the last of the front-lineSukhoi Su-9 interceptors.pecifications (RS-2US / K-5MS)
