The U.S. State Department has made a determination approving a possible Foreign Military Sale to the Government of Poland of AGM-158B-2 Joint Air-to-Surface Standoff Missile with Extended Range All-Up-Rounds and related elements of logistics and program support for an estimated cost of $1.77 billion. The Government of Poland has requested to buy up to eight hundred twenty-one (821) AGM-158B-2 Joint Air-to-Surface Standoff Missiles with Extended Range (JASSM-ER) All-Up-Rounds. Also included are AGM-158 JASSM classified test equipment; weapon system support; test support; classified software; unclassified publications; technical documentation; transportation; U.S. Government engineering, logistics support services; and other related elements of logistics.

The AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) is a low detection standoff air-launched cruise missile developed by Lockheed Martin for the United States Armed Forces. It is a large, stealthy long-range weapon with a 1,000-pound (450 kg) armor piercing warhead. It completed testing and entered service with the U.S. Air Force in 2009, and has entered foreign service in Australia, Finland, and Poland as of 2014. An extended range version of the missile, the AGM-158B JASSM-ER (Joint Air-to-Surface Standoff Missile-Extended Range), entered service in 2014 as well as an anti-ship derivative, the AGM-158C LRASM (Long Range Anti-Ship Missile), in 2018. By September 2016, Lockheed Martin had delivered 2,000 total JASSMs comprising both variants to the U.S. Air Force.

The US Air Force studied various improvements to the AGM-158, resulting in the development of the JASSM-Extended Range (JASSM-ER). 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) as compared to the JASSM’s range of about 230 mi (370 km). Other possible improvements were studied but ultimately not pursued, including a submunition dispenser warhead, new types of homing head, and a new engine giving ranges in excess of 620 mi (1,000 km). The JASSM-ER has 70% hardware commonality and 95% software commonality with the original AGM-158 JASSM. Although the B-1 was initially the only aircraft able to deploy it, it was later integrated onto the B-52, F-15E, and F-16.

In 2014, Poland requested US Congressional approval for the purchase of the AGM-158 JASSM to extend the deep penetration strike capabilities of their F-16 Block 52+ fighters. Poland signed a $250 million contract to upgrade its F-16s and equip the jets with (AGM-158) JASSM advanced cruise missiles in a ceremony at Poznan AB, Poland, on 11 December 2014. In December 2015 the production contract for Lot 13 was signed. The contract includes 140 JASSMs for Finland, Poland and the US, 140 JASSM-ER missiles for the US, and data, tooling and test equipment. It is said to be the last production lot that will include non-ER versions. Poland’s first modified F-16s should be ready by 2017, when the first missiles are delivered. The work is scheduled to be complete by June 29, 2019.
