Oshkosh Defense

Oshkosh Defense LLC designs, manufactures and sustains tactical wheeled vehicles, autonomous launchers and weapons-integration systems for the U.S. military and allied governments. Its fleets move troops, fuel, ammunition, air-defense systems and cargo in combat and austere environments. The business also supplies parts, training, field support and upgrades across the vehicle lifecycle.

Oshkosh Corporation reports Defense inside its Transport segment with Oshkosh Delivery, including the U.S. Postal Service Next Generation Delivery Vehicle (NGDV). Public segment margins and backlog therefore combine Defense with Delivery Vehicles unless Oshkosh separately discloses Defense sales.

Heavy & Medium Tactical Vehicles

The Family of Heavy Tactical Vehicles (FHTV) includes HEMTT, Palletized Load System (PLS), Heavy Equipment Transporter and related trailers for logistics, recovery and equipment transport. FHTV V is a requirements contract with a potential ceiling rather than a fully funded order. The Family of Medium Tactical Vehicles (FMTV) A2 spans 4×4 and 6×6 cargo, wrecker, low-velocity airdrop and other mission variants; Oshkosh announced $142 million of U.S. and international FMTV A2 orders in June 2026.

Light Tactical, Autonomous Fires & Weapon Integration

Oshkosh developed and produced the Joint Light Tactical Vehicle (JLTV), while domestic production under its original contract wound down in 2025 after AM General won the follow-on production competition. Oshkosh continues international JLTV activity, sustainment and derivative development. ROGUE-Fires is a semi-autonomous missile-launching vehicle derived from the JLTV family; the Marine Corps placed two Block 2 delivery orders totaling $92 million in June 2026. Oshkosh also integrates the 30 mm Medium Caliber Weapon System on Stryker infantry carrier vehicles.

Lifecycle Support & Digital Sustainment

Oshkosh Defense provides parts, field service, training, fleet modernization and lifecycle support. During Valiant Shield 2026, Oshkosh Defense and Marine Depot Maintenance Command demonstrated secure point-of-need production of an approved LVSR replacement part in Japan and Georgia using a configuration-controlled digital sustainment workflow, illustrating a potential path to shorten repair timelines for long-lead or obsolete parts.

Oshkosh Corporation generated $10.42 billion of consolidated sales in 2025. Defense sales were $1.628 billion, down from $2.052 billion in 2024 as domestic JLTV volume fell. The decline continued in the first half of 2026: Defense sales were $570.7 million versus $784.7 million a year earlier, a 27.3% decrease. Delivery Vehicle volume partly offset the Defense decline inside Transport.

At 30 June 2026, consolidated backlog was $14.75 billion and Transport backlog was $6.05 billion, down 9.8% year over year. Neither figure is standalone Defense backlog. Current Defense demand rests on FHTV and FMTV A2 orders, ROGUE-Fires, Stryker weapon integration, international vehicle sales and lifecycle sustainment. Oshkosh’s updated 2026 parent outlook calls for approximately $11.2 billion of sales, $10.50 of GAAP diluted earnings per share and $11.00 of adjusted diluted earnings per share.

Transport operating margin was 2.9% in Q2 2026. Management attributed the year-over-year pressure to adverse sales mix, higher warranty expense on a defense vehicle program and higher manufacturing overhead, partly offset by an NGDV aftermarket-rights performance obligation. The $6.05 billion Transport backlog provides demand visibility but combines Defense and Delivery Vehicles, may be modified or canceled and is not equivalent to funded Defense backlog.

Watch funded order conversion under FHTV and FMTV, the pace of the Defense sales decline, warranty and manufacturing performance, international tactical-vehicle demand, NGDV execution and whether ROGUE-Fires expands from limited orders into a sustained production line.

Oshkosh Defense’s strongest advantage is its installed base across Army HEMTT, PLS and FMTV fleets. Existing tooling, technical data, trained maintainers, spare-parts networks and qualification history can reduce customer risk when additional variants, upgrades or sustainment work are ordered. TAK-4 suspension, severe-duty manufacturing and systems-integration experience add technical depth. The limit is equally clear: incumbency does not guarantee the next competition, as the JLTV follow-on award demonstrated. Requirements contracts create a purchasing path but not guaranteed revenue.

U.S. government sales represented about 21% of Oshkosh Corporation’s consolidated sales in the first half of 2026, creating exposure to appropriations, continuing resolutions, procurement reprioritization and order timing. Domestic JLTV production under Oshkosh’s original contract has ended. Fixed-price and long-term programs expose the company to labor, material, warranty and manufacturing execution risk. Q2 2026 included higher warranty expense tied to a defense vehicle program. International sales depend on export approvals, allied budgets and local-content requirements. Parent reporting can obscure Defense economics because Transport combines Defense with Delivery Vehicles.

Ownership & Major Holdings

Oshkosh Corporation traces its roots to the Wisconsin Duplex Auto Company, founded in 1917. Its military position expanded through major tactical-vehicle programs including HEMTT, FMTV and JLTV, then broadened into Stryker weapon integration, autonomous fires and lifecycle sustainment. Oshkosh Defense LLC is an operating business within the public parent rather than a separately listed issuer.

The competitive picture changed when AM General won the follow-on domestic JLTV production contract in 2023, and Oshkosh completed production under its original domestic JLTV contract in 2025. Oshkosh remains a major U.S. heavy- and medium-tactical-vehicle incumbent while pursuing newer growth in ROGUE-Fires, international mobility, fleet modernization and digital sustainment.
