Johns Hopkins APL Delivers Prototype Defense Planning and Assessment Tool to USS Bunker Hill

In January, the guided-missile cruiser USS Bunker Hill (CG 52) — part of the Theodore Roosevelt Carrier Strike Group — left San Diego for a scheduled Indo-Pacific deployment. Along with 6,000 service members spread between several ships is a new experimental unit designed by the Johns Hopkins Applied Physics Laboratory that could one day change the way the Navy plans for defeating anti-ship missile attacks.

The hard kill/soft kill (HK/SK) Performance Assessment Tool (HaSPAT) helps the warfighter understand the planned defensive posture and evaluate combat system performance before an enemy attack. It also balances weapon inventory by advising what’s available and keeping enough weapons back for individual defense measures. APL deployed HaSPAT on the Bunker Hill to get warfighter feedback that will be essential to developing new engagement coordination capabilities for the fleet.

SK sensors detect signatures from weapons and then use electromagnetic countermeasures to disrupt them. HK countermeasures include physical weapons, such as projectiles, to destroy or damage incoming fire.
