Budget figures
$74.9M discretionary + $13.0M one-time reconciliation. Discretionary change vs FY2025 enacted: -30.6%.
Two official figures, one label— reconciled below
Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows that the R-2/P-40 J-book program line excludes — advance procurement in an ordinary year, and in FY2026 the one-time reconciliation appropriation as well. Each row below names the one it is. How the two bases relate →
FY26 Request · $87.9M TOA − $74.9M J-book line = 13.0M (87.9 − 74.9 = 13.0) — $13.0M of one-time FY2026 reconciliation money accounts for this gap — not advance procurement
Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.

Description
Mission — Air & Missile Defense Radar (AMDR) System
The Air and Missile Defense Radar (AMDR) program consists of the AN/SPY-6(V) Family Of Radars (FoR): - AN/SPY-6(V)1 (DDG 51 Arleigh Burke class Flight III guided missile destroyer) - AN/SPY-6(V)2 (Nimitz class CVN, America class LHA, and San Antonio class LPD) - AN/SPY-6(V)3 (Ford class CVN, Constellation class FFG) - AN/SPY-6(V)4 (DDG 51 Arleigh Burke class Flight IIA guided missile destroyer backfit) AN/SPY-6(V)1 will provide multi-mission capabilities, simultaneously supporting both long range, exoatmospheric detection, tracking and discrimination of ballistic missiles, as well as Area and Self Defense against air and surface threats. For the Ballistic Missile Defense (BMD) capability, increased radar sensitivity and bandwidth over current radar systems are needed to detect, track and support engagements of advanced ballistic missile threats at the required ranges, concurrent with Area and Self Defense against Air and Surface threats. For the Area Air Defense and Self Defense capability, increased sensitivity and clutter capabilities are needed to detect, react to, and engage stressing Very Low Observable/Very Low Flyer (VLO/VLF) threats in the presence of heavy land, sea, and rain clutter. This effort provides for the development of an active phased array radar with the required capabilities to address the evolving threat. The AN/SPY-6(V) FoR will obtain performance and technology enhancements throughout their service life based upon an approach that includes modularity of hardware and software, a scalable design and Open Architecture (OA). AN/SPY-6(V)2 and (V)3 (Enterprise Air Surveillance Radar (EASR) will provide multi-mission capabilities, simultaneously supporting Air Traffic Control (ATC), situational awareness, and ship self-defense against Air and Surface threats. For these missions, increased clutter capability, short-range detection and tracking, and special weather waveforms are needed. AN/SPY-6(V)3 is the primary air surveillance radar supporting ship self-defense, situational awareness and Air Traffic Control (ATC) for Ford class CVNs. For other ship classes, AN/SPY-6(V)2 is the primary radar for self-defense and situational awareness with the ancillary role of supporting ATC by resolving SPN-50 mast blockage for ATC. AN/SPY-6(V)4 will provide Active Electronically-Scanned Array (AESA) and digital beamforming technology for backfit to Flight IIA DDG. Backfit of SPY-6 technology on DDG 51 FLT IIA commences with non-recurring engineering efforts to scale the radar hardware and software; perform modeling and simulation to update the Concept of Operations (CONOPS), and enable SPY-6 Integrated Air and Missile Defense (IAMD) performance capabilities on FLT IIA DDGs. AN/SPY-6 Enhancements include Advanced Distributed Radar (ADR), High Efficiency High Powered Amplifier (HPA), Agnostic Signal Processing for Increased Radar Efficiency (ASPIRE) hardware development, second-source Radio Frequency (RF) Head, and Modeling and Simulation (M&S) in support of Combat System Test Beds, pivoting from software to hardware upgrades in FY25. ADR includes software enhancements that will enable multi-ship cooperative radar operations in order to support Distributed Maritime Operations (DMO) for the SPY-6 FoR. ADR transitions Receive Only Cooperative Radar (ROCR), Networked Cooperative Radar (NCR), and EMPIRE software capabilities from Office of Naval Research (ONR) to tactical development, implementation and testing. ADR software enhancements will increase radar detection performance for IAMD capabilities and enable operations with radars in receive-only mode in cooperation with other AN/SPY-6(V) radars. Agnostic Signal Processing for Increased Radar Efficiency (ASPIRE) effort will transition from ONR to address hardware options for more flexible digital beamforming, advanced signal processing, signal synthesizer architecture, and smaller digital receiver-exciter systems, resulting in efficiencies in radar size, weight, and power requirements as a key enabler to further enhance radar capabilities. HPA development will proceed and improve manufacturability and efficiency second source development to drive down costs. M&S efforts include support of Combat System and Enterprise Test Beds. The FY26 funding request supports the following efforts: SPY-6(V)1 integration efforts and associated development to support AEGIS Baseline 10 integration, advanced radar capability testing at the Advanced Radar Development Evaluation Laboratory (ARDEL), and integration with the AEGIS Virtual Test Environment (VTE). Integration efforts and associated development for AN/SPY-6(V)2 and (V)3 (Enterprise Air Surveillance Radar (EASR)) to integrate with Ship Self Defense System (SSDS) Baseline 12 and meet the performance requirements contained in the Battlespace Awareness Interface Control Document/Drawing (ICD). This includes continued testing at the Land Based Test Site and integration efforts with the SYY-1 Air Traffic Control System and Cooperative Engagement Capability. AN/SPY-6(V)4 FLT IIA backfit efforts will continue with land-based system testing at Advanced Radar Development Laboratory (ARDEL), combat system integration testing at Combat System Engineering Development Site (CSEDS), system-level requirements updates, software defect correction, SPY-6(V)4 power and hardware integration risk reduction testing, and developmental efforts leading to delivery of SPY-6(V)4 radar equipment to DDG 91 in FY26. SPY-6 enhancement efforts include integration and testing of second-source RF Heads, testing of the high efficiency HPA, and continued M&S efforts to support Combat System Test Beds.

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.

Oversight
GAO oversight of this program
GAO assessed Air and Missile Defense Radar (AMDR) in its June 2025 Weapon Systems Annual Assessment, as a Navy MDAP program.
“The Navy's AMDR is a radar program supporting surface warfare and integrated air and missile defense. The Navy expects AMDR's family of radars to provide increased sensitivity for long-range detection to improve ballistic missile defense against advanced threats. The Navy is also developing a radar suite controller to provide integrated air and missile defense for DDG 51 Flight III destroyers. In January 2023, the Navy added two Enterprise Air Surveillance Radar variants to the program, and in February 2024, the Navy added a fourth radar variant. This family of variants will provide radars for other ship classes.”

“The Navy's AMDR is a next-generation radar program supporting surface warfare and integrated air and missile defense. The Navy expects AMDR's family of radars—beginning with the AN/SPY-6(V)1—to provide increased sensitivity for long-range detection to improve ballistic missile defense against advanced threats. The Navy is also developing a radar suite controller to interface with an updated Aegis combat system (ACS) to provide integrated air and missile defense for DDG 51 Flight III destroyers. In January 2023, the Navy added two Enterprise Air Surveillance Radar (EASR) variants of the AN/SPY-6 radar to the program. These variants will provide next generation radars for other ship classes.”
