AKA: LEAP;RIM-161A;Standard 3 ER;Standard SM-3. Status: Active. First Launch: 1999-09-24. Last Launch: 2018-12-10. Number: 38 . Gross mass: 1,500 kg (3,300 lb). Height: 6.55 m (21.48 ft). Diameter: 0.53 m (1.73 ft). Span: 1.57 m (5.15 ft). Apogee: 160 km (90 mi).
The SM-3 was a derivative of the Standard SM-2ER Block IV using the LEAP (Lightweight Exo-Atmospheric Projectile) homing vehicle to give AEGIS naval vessels theater anti-ballistic missile capability. The two rocket stages of the SM-2ER Block IV were supplemented by a third stage, the Alliant Techsystems Advanced Solid Axial Stage (ASAS). A GPS-Aided Inertial Navigation System was used to guide the missile to near the predicted impact point, with the LEAP making the final hit-to-kill intercept. AEGIS launching ships required updates to computer hardware and software in order to operate the missile.
The LEAP and its Forward-Looking Infrared sensor were first tested in four Terrier/LEAP launches between 1992 to 1995. However both intercepts attempted in the series were failures. The first launch of a complete SM-3 missile came in September 1999. In January 2002 the first successful intercept of an Aries ballistic missile target was achieved. Testing thereafter proved the capability of the missile against more difficult targets and scenarios. In 2008 the system was modified in a matter of weeks to successfully shoot down an errant American satellite.

Launch Vehicle: SM-3.The classifed NRO USA 193 spacecraft, launched in 2006, suffered a complete failure of its on-board propulsion system, putting the satellite in a rapidly-decaying orbit. The Pentagon said that the hydrazine propellant aboard consituted a risk and announced they would shoot the satellite down. The real objective may have been to demonstrated US antisatellite capability after a Chinese test in 2007. In any case, on 21 February 2008 the satellite was down to a 242 km x 257 km orbit. At 03:26 GMT an SM-3 missile was fired from the Aegis cruiser USS Lake Erie stationed west of Hawaii, to intercept the satellite. The hit-to-kill warhead successfully rammed the satellite, breaking it up into 153 catalogued items of debris with perigees of 170-250 km and apogees of up to 2700 km.
