The same month, a $38-billion Israeli arms package over the next 10 years – the largest of its kind ever – was finalized and signed[…]In late November, the State Department approved another transaction- the acquisition of 70 AGM-158B JASSM-ER (extended range) missiles for Poland. The deal undeservedly failed to attract much attention. In fact, it matters much and changes a lot.
The prospects for the acquisition of the extended range version were discussed as far back as 2014. The US obviously procrastinated due to political considerations. The decision to make the deal go through makes Poland the first state outside the United States to acquire the JASSM-ER.
In 2014, Poland signed a contract to procure the JASSM AGM-158A version for its F-16C/D jets. The stealth missile is designed to destroy ground targets at distances 370+km (230 mi). As of 2014, the JASSM had also entered service in Australia and Finland.
The 370 km is a great range for the purpose of self-defense. But Poland badly wanted strategic conventional first strike capability. With the JASSM-ER deal reached, its dream has come true. Using a more efficient engine and larger fuel volume in an airframe with the same external dimensions as the JASSM, the JASSM-ER has an operational range of 1000+km (620 mi) – an effective stealth weapon to knock out key stationary infrastructure sites located deep in Russia’s territory. The weapon boasts a penetrating warhead.
With the AGM-158A expected to become fully operational this year, Poland has the aircraft and crews ready to receive the extended range version. The JASSM-ER has 70% hardware commonality and 95% software commonality with the original AGM-158 JASSM.
