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 $78.2M for FY2024; the PB2026 book reported $197.7M as actual total obligation authority — $119.5M above the request. 197.7 − 78.2 = 119.5 USD millions — the compact figures above are rounded for reading.

Description
Description — Sidewinder
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). This inner-boundary missile provides fighter aircrew with the first shot, first kill opportunities while conducting air combat maneuvering which is essential for aircrew survival. The AIM-9X delivers these opportunities with unmatched offensive and defensive capabilities against threats within the inner-boundary, even when IR countermeasures are employed. The AIM-9X also supports air superiority in the Beyond Visual Range air-to-air battle. Anti-tamper features have been incorporated to protect improvements inherent in this design. The AIM-9X Block II missile provides the Joint Force with fighter aircraft lethality and survivability necessary to counter threats identified in the Chief of Naval Operations Guidance and the Interim National Defense Strategic Guidance. AIM-9X is a Post Milestone C, Acquisition Category IC joint service program led by the Department of the Navy (DoN). In June 2011, the Milestone Decision Authority established the AIM-9X Block II missile program which was approved for entry at Milestone C for Low Rate Initial Production. The Block I program ended with section 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, and the APB was re-established. In February 2019, the AIM-9X Block II Sidewinder APB for DoN and United States Air Force (USAF) was revised to increase total missile procurements from 6,000 to 11,635 missiles and to extend missile procurements. Production currently ends in 2040. The current APB quantity of 11,635 missiles is made up of 5,326 DoN missiles and 6,309 USAF missiles. In addition to the 5,326 Block II missiles in the APB, this budget includes 1,289 Block I missiles and an additional 271 missiles (FY 2024) for replacement of Navy stock expended in support of Ukraine, for a total of 6,886 missiles. Total Cost to Complete should reflect $1,389.546.
Justification
Justification — Sidewinder
The FY 2026 request was reduced by $0.104 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." The FY 2026 budget provides funding to procure the 12th lot of FRP AIM-9X Block II (Blk II) missiles. Additionally, FY 2026 continues procurement of upgraded Inertial Measurement Unit Guidance Units. Procurement funding in FY 2026 through FY 2030 was realigned to the RDT&E budget (PE 0207161N, PU 0457) for AIM-9X digital fuze and Systems Improvement Program (SIP) IV efforts, including development of hardware and software improvements. FY 2024 and FY 2025 quantities of 387 and 157, respectively, are properly displayed on the P-5. For FY 2025, the P-5 does not include supplemental funding or QTYs. The program unit costs are based on quantities procured by the DoN, USAF, Army, Foreign Military Sales, and other customers. Total Program quantity by service includes a mix of All Up Round (AUR) missiles and Captive Air Training Missiles (CATMs). Due to AIM-9X inventories being below the USN Total Munitions Requirement, the program will procure the maximum quantity of missiles with the provided funding in accordance with Title 10, US Code Section 2308 BUY-TO-BUDGET ACQUISITION. FY 2024 includes supplemental funding from Ukraine Security Supplemental Appropriations Act, 2024 (Division B of Public Law 118-50). DON has received $129.244 million for the procurement of 271 AIM-9X Block II missiles for the replacement of Navy stock. This results in an increase in FY 2024 quantities from 116 (actual) to 387. Note - FY 2024 actual quantities, prior to receipt of supplemental, were reduced from 147 (as reflected in the FY 2025 budget submission) to 116 due to increased AUR unit costs and realignment of funds to Production Technical support for cyber security efforts FY 2025 matches the Base for Reprogramming Actions, DD 1414 and does not include supplemental funding from Israel Security Supplemental Appropriations Act, 2024 (Division A of Public Law 118-50) and Ukraine Security Supplemental Appropriations Act, 2024 (Division B of Public Law 118-50). In FY 2025, DON has received $196.608 million for the procurement of AIM-9X Block II missiles for the replacement of Navy stock. This results in an increase in FY 2025 quantities from 157 to 582.

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.
