## Summary

Project 675056 — B-52 Radar Modernization Program (RMP) requests $106.9M in FY2027, 7.2% of the $1.48B requested for program element 0101113F, down 30% on FY2026. 1 R-2A activity decomposes the request. Boeing is the largest named R-3 performer at $83.5M, 78% of the project's FY2027 R-3 total.

## What project 675056 buys

The B-52 Radar Modernization Program (RMP) supports nuclear and conventional operations by replacing the current AN/APQ-166 radar on the B-52 aircraft with the AN/APQ-188 radar. The APQ-166 system is increasingly difficult to sustain due to Diminishing Manufacturing Sources & obsolescent technologies, and the current failure rate places long-duration missions at risk. This modernization program will encompass the radar antenna array, 12 individual Line Replaceable Units (LRU), the radar control panel, and the Group A allocation that comprise the entire radar system. RMP will take advantage of advances in technology and on-going development efforts to acquire, to the maximum extent possible, previously developed radar systems and integrate them into the B-52. The use of new technology will increase both the overall reliability of the radar system and the capabilities for new missions. RMP will allow the operational command (AF Global Strike Command) to fully utilize the capabilities of the B-52 aircraft to employ an array of nuclear and conventional weapons and perform mission-essential navigation and weather avoidance functions. AF Global Strike Command approved the removal of the radome from the baseline program for considerations of cost control and satisfactory legacy radome performance. In addition, applicable training devices for the new radar subsystem must also be developed, modified, and/or upgraded in conjunction with the aircraft modifications. This modification includes the installation of Engineering and Manufacturing Development (EMD) kits on two B-52 test aircraft to support Developmental/Operational Test and Evaluation (DT/OT). This program upgrades one B-52 Software Integration Lab (SIL) with radar functionality and builds a new Radar Development Lab and a new Radar SIL. Additionally, this program will develop a desktop training tool.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.

## Named R-3 performers

| Performer | $M | Share of this project's FY2027 R-3 total |
|---|---|---|
| Boeing | 83.5 | 78% |
| Edwards AFB | 10.4 | 9.7% |
| AFLCMC/FZA | 6.0 | 5.7% |
| AFOTEC | 1.4 | 1.3% |

> Budget-justification contract funding, not obligations. Shares need not reach 100% — unnamed and government work is in the denominator.

## Activities (R-2A) — 1

> 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.

### Radar Modernization Program (RMP)

Will continue Agile and incremental software code development for version 1.0; continue development flight testing; create, test, and deploy software fix releases to integration labs and development flight test aircraft; prepare for Initial Operational Test and Evaluation (IOT&E).

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
