What project 456 buys
The Advanced Operational Energy Mobility (OEM) portfolio accelerates Joint Force freedom of maneuver by transforming assured energy access into operational reach, tempo, and sustained movement across contested, austere, and denied environments. Building on prior Operational Energy Surety investments, P-456 shifts emphasis toward operationalized mobility outcomes, enabling forces to move farther, persist longer, reduce identifying heat and acoustic signatures, and maneuver with reduced logistical burden across air, land, and maritime domains. These efforts directly align with National Defense Strategy priorities, including Indo-Pacific operations, contested logistics, Arctic access, and distributed air, maritime, and land maneuver. The portfolio emphasizes 1) Air Mobility 2) Land and Maritime Mobility, and 3) integrating multi-domain operational energy solutions. Together these elements triangulate operational energy innovation into a maneuvering advantage, increasing operational tempo, duration, and force employment. OEM delivers critical enablers for operational flexibility by expanding freedom of maneuver through: • Aviation Mobility - advances energy delivery, airframes, propulsion, and intelligent power management extending range, persistence, and freedom of action of crewed and uncrewed aviation platforms, reducing sortie demand while enabling operational mobility and aviation overmatch. • Land and Maritime Mobility - advances operational duration for ground/maritime platforms including extending operational reach, enabling silent watch and silent mobility, and maintaining power in austere and contested environments. These efforts ensure energy availability at the tactical edge while enabling crewed, uncrewed, and autonomous maneuver across land, sea, and sub-surface domains. • Operational Energy Integration – advances and enables energy technologies across domains, platforms, and electrical grids, enhancing lethality, mobility, and maneuver in contested environments. OE integration includes operationalizing energy for high-powered directed energy weapons and radar systems in support of Golden Dome, producing energy at the tactical edge, and enabling energy prepositioning and storage.
Project 456 funding, FY2026–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
In FY 2027, OEM strengthens operational readiness and empowers warfighters to successfully execute missions by: • Golden Dome and High-Power Energy Requirements: Integrating directed energy component technologies into platforms and weapons systems, conducting power conditioning, increasing the domestic supply chain in support of advanced…
