This activity requests $96.1M in FY2027, 35% of project 675344, up 93% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 675344 of PE 0101126F. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

Continue airworthiness analysis, and test activities to support ground and flight test events. Finalize hardware design to include changes to Line Replaceable Units (LRUs) and wiring. Order Group A and Group B hardware for on-aircraft testing. Conduct software testing and ground testing. Each Group A Kit (Install Kit) includes an aircraft wiring harness kit and a hardware kit. Each Group B Kit (Equipment Kit) is a Load Adjustable Modular (LAM) Pylon and associated Group B equipment. Expand external carriage opportunities to Advance 5,000-pound (A5K) Guided Bomb Unit (GBU-72) to include Software and Hardware development.

FY2026 to FY2027 change

The External Heavy-Stores Pylon Program is operating to an accelerated program schedule with Initial Operating Capability (IOC) targeted for Q1 FY 2029. In order to support these schedule commitments, the program requires increased funding to support FY 2027 activities.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

Conduct Computational Fluid Dynamic (CFD) and wind tunnel testing of pylon/weapon combinations. Begin hardware design to include changes to aircraft Line Replaceable Units (LRUs) and wiring. Each Group A Kit (Install Kit) includes an aircraft wiring harness kit and a hardware kit. Each Group B Kit (Equipment Kit) is a Load Adjustable Modular (LAM) Pylon, External Multi-purpose Rotary Launcher (E-MRPL) and associated Group B equipment.

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 35% of project 675344's FY2027 request and 35% of PE 0101126F's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
