### Project 0457 — AIM-9X

The AIM-9X Block II Sidewinder (AIM-9X Blk II) delivers a launch and leave, air combat munition that uses passive Infrared energy to acquire and track enemy air targets that employ advanced infrared countermeasures and is a critical component of fighter aircraft loadout required by the Chief of Naval Operations Guidance and the National Defense Strategy. This line item continues technical refresh of hardware and software and develops advanced capabilities to maintain threshold requirements. Primarily, the program will develop new hardware and software solutions to pace evolutions in threat aircraft countermeasure technology and redesign, develop, and integrate components facing obsolescence. Integration activities will focus on compatibility with advanced platforms. The program will deliver increased capability to the warfighter by incrementally fielding missile software updates to optimize hardware and incorporate capabilities based on updated intelligence of threat countermeasures. The AIM-9X Compact Variant (CV) repackages the AIM-9X Blk II technology into a compact airframe optimized for internal carriage on advanced aircraft with improved kinematic performance. The program will deliver increased capability to the warfighter with greater standoff range, increased aircraft weapon station capacity, and maintains inner boundary performance. In FY 2027, the program will execute engineering, manufacturing, and development for the phase 4 of the System Improvement Program (SIP) hardware and software effort. Specifically, development of Operational Flight Software (OFS) 11.6X will continue. The SIP IV hardware Engineering Change Proposal (ECP) will be complete Q2 FY 2027. In addition, the program will continue AIM-9X CV risk reduction development activities to advance hardware and software designs. The AIM-9X CV integration activities will focus on ensuring compatibility with advanced platforms. CV risk reduction efforts were funded in FY 2025 and FY 2026 Product Development under SIP risk reduction. This effort is not an FY 2027 new start.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** RTX / Raytheon (103.5, 85%), NAWCWD (12.4, 10%), NAWCAD (4.1, 3.4%), COMOPTEVFOR (1.0, 0.9%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Product Development | 27.4 | 30.9 | 29.9 |
| Compact Variant (CV) | 0.6 | 0.6 | 83.3 |
| Management Services | 0.3 | 0.2 | 0.2 |
| Test and Evaluation Activities and Support | 2.3 | 2.9 | 9.1 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Industry primes | 99% | 121.1 |
| Government labs & warfare centers | 1.0% | 1.2 |
| Other / unspecified | 0.2% | 0.2 |

**Top named industry performers:** RTX / Raytheon ($103.5M, 85%), NAWCWD ($12.4M, 10%), NAWCAD ($4.1M, 3.4%).

## Mission & acquisition strategy

The AIM-9X Block II Sidewinder (AIM-9X Blk II) continues the evolution of the AIM-9 series of missiles. This missile program delivers a launch and leave, air combat munition that uses passive Infrared (IR) energy to acquire and track enemy air targets and complements the radar guided Advanced Medium Range Air-to-Air Missile (AMRAAM). The missile provides fighter aircrew with the first shot, first kill opportunities that are essential for survival during air combat maneuvering in the visual arena. The AIM-9X delivers these opportunities with unmatched offensive and defensive capabilities against inner boundary threats, even when IR countermeasures are employed.

Milestone C decision for LRIP was held June 24, 2011. The program received DON Initial Operational Capability in March 2015 and Full Rate Production (FRP) approval in August 2015. The program awarded FRP-11 in June 2025. FRP 13 will award March 2027. AIM-9X annual procurements will continue beyond the FYDP.
