## What the FY2027 request buys

**FY2027 planned work.** Procure (V)3 EDM and begin Engineering Change Proposal (ECP) development for the AN/SPN-50(V)3 to address component obsolescence; the (V)2 is no longer procurable after FY27. The (V)3 ECP will replace obsolete parts and integrate modern software solutions that enhance performance and interoperability with other systems.
