US Navy tests RF decoy housed in Harpoon missile on Poseidon MPA

A US Navy P-8A Poseidon maritime patrol aircraft from the Air Test and Evaluation Squadron (VX) 20 recently flew an airworthiness test of a pod-mounted radio frequency countermeasure (RFCM) prototype at NAWCAD’s Atlantic Test Ranges.

The first-of-its-kind RFCM decoy pod, which integrates the AN/ALE-55 fiber optic towed decoy from PMA-272 into a shell, could allow the P-8A to thwart enemy radio frequency missile attacks.

The navy developed the shell design based on the certified AGM-84 Harpoon missile, and then incorporated unique tracks and housing to fit and deploy the decoy.

“This has the potential to be a game-changer for protecting the warfighter,” said Capt. Eric Gardner, program manager for the Maritime Patrol and Reconnaissance Aircraft Program Office (PMA-290). “We continue to look for ways to enhance capabilities that allow the fleet to be successful.”

Getting the pod into testing, in just over a year, took a complete team effort.

Constantly looking for upgrades to the P-8A, PMA-290 set out to find a solution to a potential threat from surface-to-air radio frequency missiles.

Outlining their needs and running lead on the project, PMA-290 brought in the Advanced Tactical Aircraft Protection Systems Program Office (PMA-272), the Rapid Prototyping, Experimentation & Demonstration (RPED) team, and the NAWCAD Aircraft Prototype Systems Division (APSD) to get the ball rolling.

By employing the assistant secretary of the Navy for research, development and acquisition’s delegation of other transactions authority (OTA) for prototype projects, PMA-290 and NAWCAD were able to complete a one-of-a-kind contract with BAE Systems to develop the RFCM pod’s additional internal equipment suite.

APSD and BAE leveraged the established AN/ALE-55 electrical design to accommodate the suite’s installation.

“A lot of the challenge and effort went into designing, to our best estimates, for what BAE was expected to put in the pod,” said Michael Hansell, the leading APSD engineer for the project. “We had to adapt and redesign rapidly. We worked as fast as possible to support PMA-290 and RPED to make sure we could pivot and adjust to meet established timelines.”

Constant tweaks were needed as the teams continued to hone in on a capable design.

“Michael Hansell and his team’s flexibility and willingness to go above and beyond, to work through issues and prepare for BAE, was key in getting [the pod design and build] done in a timely manner,” said James Sherman, the APSD project lead.

The Naval Innovative Science & Engineering (NISE) program funded the project, which provided the means to conceptualize, prototype, build, and test this new capability for the navy.

This funding accelerated the design and manufacturing cycle for the prototype to just under six months.

The teams were also able to utilize PMA-272’s F/A-18 lab equipment to speed up the timeline.

All this teamwork culminated in the successful airworthiness test with VX-20.

Following the test, the pod went to Naval Air Weapons Station China Lake, California where it successfully completed effectiveness testing, March 21-26. It will now continue to be tested at a system level leading to platform integration through planned capability fielding phases.
