Using a more efficient engine and larger fuel volume in an airframe with the same external dimensions as the JASSM, the JASSM-ER is intended to have a range of over 575 mi (925 km) compared to the JASSM's range of about 230 mi (370 km).

2024年4月23日 · The JASSM (Joint Air-to-Surface Standoff Missile) is a conventional, stealthy, air-launched ground attack cruise missile designed for the U.S. Air Force and international partners. An extended range version, AGM-158B JASSM-ER, was developed alongside the standard variant, and went into service in 2014. 1

2022年7月17日 · The Joint Air-to-Surface Standoff Missile (JASSM) enables the U.S. Air Force to destroy the enemy’s war-sustaining capabilities from outside its area air defenses. There are multiple variants that make up the JASSM family of missiles: AGM-158A baseline (BL) and the Extended Range (ER) family (AGM-158B, AGM-158B-2, AGM-158B-3 and AGM-158D).

2025年1月17日 · The JASSM-ER features a larger internal fuel tank and a more efficient turbofan engine, allowing it to reach targets up to 1,000 km away, compared to the standard JASSM's range of 370 km. Despite these enhancements, the JASSM and JASSM-ER share identical airframes, making them indistinguishable by appearance alone.

2013年7月5日 · AGM-158B JASSM-ER is an extended range variant of JASSM. It is intended to fly longer ranges (almost double the range of base JASSM) as it integrates a highly efficient engine and larger fuel tank. The missile can be integrated into B-1 aircraft. Low rate production of JASSM-ER was authorised in January 2011.

Engine: A solid-fuel rocket engine that provides significant range. Wings: Short wings provide stability and maneuverability during flight. Fuselage: The missile body, housing all primary …

JASSM-ER is an extended long-range, conventional, air-to-ground, precision-guided standoff missile designed to meet the needs of U.S. Warfighters. JASSM-ER shares the same powerful...

The JASSM-Extended Range (JASSM-ER) version uses the same baseline body, but a new engine and fuel system that increases range to more than 500 miles. The ER was cleared for combat use on the B-1B in 2015, reached full operational capability on the F-15E in 2018, and planned for use on all fighter/bomber platforms.

As a propulsion system, the J402 turbojet engine with advanced compressor and fuel system is used. The combined guidance system, along with the thermal imaging CNS borrowed from the planing bomb AGM-130 (operates in the final guidance area), uses an inertial control system with correction according to NAVSTAR and software and hardware for ...
