    Az nem lehet, hogy két fokozatú a rakétahajtómű? Tehát egy gyorsító és egy "utazó" hajtómű működik.

    Ezt találtam:

    No spare missiles are carried on the vehicle and fresh missiles are brought up by a truck and loaded with a light crane. A well-trained crew of three can load four missiles in about two minutes. The missile is designated the R440 and weighs 84 kg, has an overall length of 2.89 m, span of 0.54 m and a diameter of 0.15 m. The missile complete with its transport/launch container weighs 100 kg. The HE high-energy focused fragmentation warhead in the centre of the missile weighs 15 kg, has a lethal radius of 8 m for the 2,300 m/s velocity fragments and is activated in the original R440 missiles by either the infrared proximity fuze (the fuze is commanded to activate 350 m before interception) or back-up contact fuze. The missile has an SNPE Lens III rocket motor with 25.45 kg of solid propellant powder. The missile reaches a maximum speed of 750 m/s in 2.8 seconds. The Naval Crotale fires a slightly modified missile, the R440N fitted with a Thomson-CSF FPE pulse-Doppler I/J-band proximity fuze. For 1 m{2} radar fluctuating cross-section targets with velocities of 50 and 250 m/s respectively the engagement parameters in Table 1 apply.

    Table 1. Velocity 50 m/s 250 m/s Head-on target (maximum operational intercept range) >10,000 m 9,500 m (minimum operational intercept range) 500 m 500 m Crossing target (maximum operational intercept range) 9,700 m 5,500 m (minimum operational intercept range) 500 m 2,000 m Target altitude (maximum) >5,000 m 4,500 m (minimum) 15 m 15 m {ct} The Single-Shot Kill Probability for a single missile is 0.8 and for a salvo of two 0.96.
