The 240 mm FRAG-HE F-961 is only one type of 240 mm artillery rocket, the FRAG-HE F-961, is likely to be encountered although chemical and smoke rockets were reported at one time. The 240 mm FRAG-HE F-961 is a spin-stabilised rocket resembling an elongated conventional artillery projectile. The streamlined ogive has a threaded fuze well for a nose-mounted PD V-24 fuze, although the Israeli equivalent is provided with a NATO-standard PD M577 with an optional 0.05 second delay mode. The latter fuze is not armed
until it is at least 200 m from the launch point. Proximity fuzes were offered as an option on Israeli produced 240 mm rockets. The warhead is a machined steel forging threaded onto the rocket motor. On the 240 mm FRAG-HE the explosive filling is 27.15 kg of TNT; on the Israeli equivalent it is 18.3 kg of TNT. In both cases detonation of the explosive fractures the steel warhead casing into approximately 12,000 fragments, creating an effective lethal area for each rocket warhead of approximately 12,000 m 2. The rocket motor casing is machined from heat-treated high-tensile alloy steel. Threaded into the base is a steel nozzle block into which 16 nozzles canted at an angle of 10º to impart stabilising spin are machined; the external diameter of each nozzle is 29.97 mm. The spin rate at launch is 14 rps, raising to 180 rps at burnout. The double-base rocket propellant is formed in seven tubular blocks, each hollow along the centre, providing a thrust of 4,000 kg and a burn time of 1.2 seconds. The propellant is ignited, via a base-mounted electrical initiator, by black powder in a bag under the forward bulkhead and above the propellant blocks. Propellant weight in the Israeli version is 24 kg. A base grid prevents the propellant blocks from shifting towards the nozzles. The maximum range of the 240 mm FRAG-HE F-961 and its Israeli equivalent is approximately 10,700 m. At that range probable error ranges are of the order of 95 m in range and 40 m in azimuth. At 10,000 m a salvo of 12 rockets can cover an area of 125,000 m 2. The Soviet 240 mm rocket system dates from the early 1950s.
