British low-visibility tactical aviation SPEAR-3 missiles may appear on the front line. For the unified air defense system of Russia, they are heat-contrast objects, detected and tracked both through the infrared channel of aviation quantum optoelectronic targeting and navigation systems such as OLS-35/50M, integrated into the architecture of Su-35S and Su-57 fighters.
Also, these aerial targets can be detected by the turret optoelectronic targeting systems 10ES1-E of the Pantsir-S1/SM air defense missile system, which are the main support for maintaining the highest noise immunity of the weapon control system of the Pantsir-S1 air defense missile system.
The SPEAR-3 missile is a hybrid modification of the GBU-53/B (SDB II) and JAGM missiles. It is equipped with a compact TJ-150 turbofan engine from Humilton-Sundstrand, which provides a flight range of up to 100 km.
The integrated guidance system includes infrared, radar and television channels, which allows the missile to accurately hit targets even in conditions of interference and difficult terrain. In the standard modification, the effective scattering area (RCS) is only 0.007–0.01 m². This makes it difficult to detect the missile by radars of Russian S-300 and S-400 complexes.
