The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Asked vs spent: the PB2024 book requested $95.6M for FY2024; the PB2026 book reported $157.7M as actual total obligation authority — $62.0M above the request. 157.666 − 95.643 = 62.023 USD millions — the compact figures above are rounded for reading.

Description
Description — Sidewinder (AIM-9X)
The AIM-9X Block II/II+ Sidewinder (AIM-9X Blk II/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 inner-boundry missile provides first shot, first kill opportunities while conducting air combat maneuvering which is essential for aircrew survival. The AIM-9X provides these opportunities with unmatched offensive and defensive capabilities against threats within the inner boundary, even when IR countermeasures are employed. The AIM-9X also provides air superiority in the Beyond Visual Range (BVR) air-to-air battle. Anti-tamper features have been incorporated to protect improvements inherent in this design. The AIM-9X Block II missile is critical for projecting power and winning decisively against current and emerging threats. AIM-9X is a Post Milestone C, Acquisition Category IC (ACAT-IC) joint service program led by the Department of the Navy (DoN). In June 2011, the Milestone Decision Authority (MDA) established the AIM-9X Block II missile program which was approved for entry at Milestone C for Low Rate Initial Production (LRIP). The Block I program ended with the Sec 2366 A/B certification and Acquisition Program Baseline (APB) for AIM-9X Block II approval on December 23, 2011. In August 2015, the program received approval for Full Rate Production (FRP), and the APB was re-established. In December 2017, the program began to procure a third variant of the missile labeled the AIM-9X Block II PLUS (Block II+) to satisfy the requirements of the Joint Strike Fighter platform. This version of the missile is being produced on the same production line as the AIM-9X Block II missile. For contracting purposes, the nomenclature of the AIM-9X Block II missile is identified as AIM-9X-2 or AIM-9X-4 and the AIM-9X Block II+ missile is identified as AIM-9X-3. The AIM-9X-4 variants are the System Improvement Program (SIP) III configuration with upgraded hardware for obsolescence that cut into Lot 21. In February 2019, the APB for DoN and USAF was revised to increase total missile procurements from 6,000 to 11,635 missiles and to extend USAF missile procurements through 2035. The current APB quantity of 11,635 missiles is made up of 5,326 DoN missiles and 6,309 USAF missiles. Funding for this exhibit contained in PE 0207161F. Funding may be used to address Diminishing Manufacturing Source (DMS) issues. This requirement supports performance of a full financial audit as required by title 10 U.S.C. Chapter 9A, Sec 240-D. Differences in USAF and USN All-Up Rounds (AUR) unit cost is the result of the variations in procurement of missile types by each service.
Justification
Justification — Sidewinder (AIM-9X)
FY 2026 provides funding to procure the twelfth lot of FRP AIM-9X Block II (Blk II) missiles for the Air Force. The program unit costs are based on quantities procured by the DoN, USAF, and Army, as well as Foreign Military Sales (FMS) customers. Total Program quantity by service includes a mix of AUR missiles Captive Air Training Missiles (CATM). In FY 2026, the Air Force will procure 173 missiles. Specifically, 149 All-Up Rounds (AURs) and 24 Captive Air Training Missiles (CATMs). Funding may be used to resolve production Diminishing Manufacturing Sources (DMS)/Material Shortages/Obsolescence issues through studies, bridge buys, life of type buys, supplier/parts replacement and qualification activities to preserve future production capabilities and capacities. Note: Procurement quantities can change based on negotiated options/pricing bands and available funding, in accordance with Title 10, U.S Code Section 3069 BUY-TO-BUDGET ACQUISITION.

Follow the dollar
No follow-the-dollar view — this program's awards haven't been crosswalked at high confidence (flows cover 312 of 1,938 programs). why coverage is partial? →
Related awards
Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →
Rows marked medium rest on evidence weaker than a program-level match, and of more than one kind. An account-based row, where the award drew from the same appropriation account as this program, is an association, not evidence that this program paid for the contract. Where the evidence is instead an FPDS acquisition-program tag or a subaward description, the program is established but which of its budget lines paid is not. An announcement link a recorded review did not leave standing is medium too. Only high rows rest on the contract naming this program with a recorded review upholding it and no recorded rejection or refutation applying.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions
