The US is producing sensors for Ukraine that will be able to hit Russian EWs and extended-range homing heads for JDAM-ER guided air bombs, — Defense Express.

The Pentagon announced the award of a $23.5 million contract to Scientific Applications and Research Associates (SARA). The contract provides for the acquisition of Home-on-GPS electronic warfare detection sensors and the integration of extended-range homing warheads on JDAM-ER guided air bombs.

These weapons will not only be able to resist the operation of EW equipment — they will also be able to target electronic warfare stations.

There is not much publicly available data on the Home-on-GPS (or HOJ) kits themselves. For the first time in 2018, the SARA company announced the creation and readiness to deliver kits for countering and defeating enemy EW assets, providing only the following details: the HOJ is compact enough, costs 10 times less than its predecessors, and its component base allows for easy integration into the guidance systems of any available high-precision air weapons.

In December 2020, the U.S. Air Force conducted tests as part of the Golden Horde precision munitions program, in which the U.S. military practiced dropping a "swarm" of GBU-39/B guided aerial bombs, each of which was equipped with SARA's HOJ sensor. The results of these tests were considered successful.

The Pentagon awarded the contract for Home-on-GPS EW countermeasures and defeat kits shortly after US Deputy Secretary of Defense Bill LaPlante admitted that GLSDBs were ineffective on the battlefield in Ukraine precisely because of countermeasures by Russian electronic warfare equipment.

At the same time, it is possible that the Army's HOJ kits could be integrated into the AGM-88 HARM anti-radar missile in the future.
