The SMD-20 Sijjil (Arabic: سجیل, English: "Baked Clay", which is a reference to divine punishment in the Qur'an) is a light fire and forget air-to-surface missile developed by Riysa. It is designed primarily for anti-tank duties, but can also be used in a general tactical role as well against fixed positions and reinforced targets.
History
Description
Warhead
The warhead is a tandem-charge HEAT warhead with a penetration value estimated to be around a meter and a half of RHA steel; the high penetration makes it useful for taking out armored targets. Notably, the missile produces very little fragmentation, making it safe for precision strikes in urban environments or when friendly forces are nearby.
Seeker
The Sijjil has a dual-mode seeker system, consisting of a millimeter wave radar seeker head, and laser beam-riding seeker equipment in the rear. Either or both of the modes can be used during launch, with the laser beam-riding mode providing improved accuracy versus moving targets and excellent resistance to jamming and deception compared to the MMW seeker, although it severely limits the missile's range and necessitates the launch aircraft to stay in the area until the missile has impacted, increasing the danger to the operator.
Propulsion
The Sijjil uses a solid-fuel rocket motor, allowing it to travel at up to 450 meters per second, giving a very short flight time to the target. The missile has enough fuel to have a 30 kilometer range, although that can be limited by the seeking mode and other conditions.
