JASSM Extended Range (JASSM-ER)
The Joint Air-to-Surface Standoff Missile (JASSM) family of missiles includes: JASSM Baseline (JASSM-BL/AGM-158A) and JASSM Extended Range (JASSM-ER/AGM-158B, AGM-158B-2, AGM-158B-3, and AGM-158D). JASSM-ER provides a long range, conventional air-to-surface, autonomous, precision-guided, low observable, standoff cruise missile compatible with fighter and bomber aircraft. JASSM-ER provides the capability to attack a variety of high value fixed or relocatable targets with precision, through preplanned missions or target-of-opportunity, deeper into enemy territory than JASSM-BL, all while minimizing the threat to launch aircraft. Aircraft integration of JASSM-ER/AGM-158B is complete on the B-1, F-15E, F-16, B-2, and B-52. Objective aircraft are F-15E, F-16, B-52, B-2, and further integration is required for the F-35. JASSM-ER/AGM-158B-2 is complete on the B-1 only. The AGM-158A, AGM-158B, and AGM-158B-2 are fielded. The AGM-158B-3 and AGM-158D are in development and will gradually insert into the production line as the new missile builds are approved and ready. Missiles accepted by the Air Force will not be returned for modification to the newest variant. Threats to JASSM survivability are being rapidly developed and fielded by near-to-peer adversaries. JASSM continued development enhances capability and provides operational flexibility against current and projected threats. This is accomplished by evaluating high payoff technology development, performing risk reduction activities, and investigating new variants and/or alternate missions that may use JASSM attributes. To maximize effectiveness of existing inventory and address findings from the field, the Air Force develops, tests, and fields improvements via software upgrades into fielded missiles and/or hardware upgrades inserted into the production line. The AGM-158B-2 is an upgrade to the existing JASSM-ER/AGM-158B, incorporating multiple development initiatives to respond to rapidly changing threats and started production in Lot 19. The AGM-158B-3 provides Military M-code capability and will begin a production cut-in starting in Lot 22. The AGM-158D provides Weapon Data Link (WDL) capability to re-target the missile, post-launch, against relocatable or higher priority targets during mission execution. The AGM-158D will begin a production cut-in starting in Lot 23.
Will continue lab development, lab/flight testing and update classified software to include mission planning. Will continue to develop the appropriate Systems Performance Models (SPM)/Missile Performance Models (MPM) for the AGM-158D and to provide the MPM for incorporation into the JASSM mission planning software on Joint Mission…

Will continue system level testing and qualification activities required for flight testing that begins in FY 2027. FY 2027 Funding ($98.792 million) will be comprised of the WDL contract ($86.927 million), Government Test support ($3.923 million), and…
Read the FY2027 plan →FY2027 planned work Directed activities to include development and demonstration of SIP related modifications within survivability, lethality, and accuracy where selections are accomplished through studies and testing to ensure effectiveness against emerging threats. Will continue evaluation activity addressing JASSM's obsolescence plan.
FY2026 to FY2027 change Funding remains consistent based on continued activities targeting safety and survivability, ensuring JASSM lethality against emergent threats.
FY2026 plans — current year Continue evaluation activity addressing JASSM's obsolescence plan. Directed activities to include safety and survivability, which are comprised of studies and testing to ensure lethality against emerging threats.
