## What project 2190 buys

The Offboard Active Decoy (Nulka) is a joint cooperative program between the United States and Australia that developed an active offboard decoy that utilizes a broadband radio frequency repeater mounted atop a hovering rocket. Nulka counters a wide variety of present and future radar guided Anti-Ship Missiles (ASMs) by radiating a large radar cross section while flying a ship-like trajectory. The United States developed the electronic payload and fire control system, while Australia developed the hovering rocket. The FY 2027 budget request includes Decoy Launcher Processor (DLP) Nulka Objective Architecture, Decoy Launch Message Converter (DLMC) backward compatibility technology with Soft Kill Coordination System (SKCS), as well as funding to commence Nulka Payload Improvements for EW capability. The Objective Architecture development will continue which provides improved Nulka decoy deployment as well as SKCS integration.

**R-3 lines of work:** Product Development; Management Services.

| NULKA Decoy Subsystem | 4.8 | 5.6 | 12.5 | +125% | [a0](https://hitchintel.com/programs/0604757N/2190/a0) |

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### NULKA Decoy Subsystem

- Continue engineering and effectiveness studies to evaluate new and existing threats; update Fly-Out Tactics table for specific platforms (as appropriate) - Continue to develop and test new Nulka library files to support new platforms with SKCS (as appropriate) - Continue DLMC Nulka Objective Architecture backward compatibility…
