Oshkosh Defense to produce Grid Aero's Lifter long-range cargo drone to improve US military logistics.

Oshkosh Defense partnered with Silicon Valley startup Grid Aero on November 2, 2026, to manufacture the Lifter family of autonomous military cargo drones in Wisconsin, marking Oshkosh’s first entry into aircraft production. The initial Lifter Lite configuration targets a 2,000-lb (907-kg) payload over a 2,000-nautical-mile (3,704-km) range, combining Grid Aero’s twin-engine piston design with Oshkosh’s high-volume defense vehicle manufacturing lines. The partnership aims to establish a pilot production line by late 2027 to scale low-cost aerial resupply for U.S. military distributed operations under the Air Force’s Agile Combat Employment concept across the Indo-Pacific.

On November 2, 2026, Oshkosh Defense and Grid Aero announced a manufacturing partnership to bring the Lifter family of autonomous cargo aircraft into serial production in Wisconsin, marking Oshkosh's first entry into aircraft manufacturing. Founded in San Leandro, California, in 2024, Grid Aero began developing its Lifter Lite in January 2025 and unveiled a full-scale prototype on August 18, 2025. The twin-engine, piston-powered cargo drone targets a 2,000-lb (907-kg) payload over 2,000 nautical miles (3,704 km), while larger variants are intended to carry up to 8,000 lb (3,629 kg). Acquisition price objectives range from $500,000 to $1 million for smaller configurations and $2.5 million to $3 million for larger aircraft, compared with more than $100 million for some conventional military transports.

Grid Aero will initially undertake low-rate production, while Oshkosh prepares a pilot manufacturing line targeted for late 2027. The objective is to produce hundreds or thousands of aircraft for moving critical supplies between dispersed U.S. military airfields, particularly across the Indo-Pacific, where the distance between operating locations and the limited availability of crewed transport aircraft complicate the distribution of relatively small cargo shipments. Oshkosh brings an industrial base comprising 37 facilities across nine U.S. states and seven countries, approximately 18,500 employees, 11,750 production workers, more than 2,000 welders and fabricators, and over 1,900 engineers. Its experience includes manufacturing more than 25,000 Joint Light Tactical Vehicles (JLTVs), although AM General secured the follow-on JLTV contract in February 2023.

The Lifter's bent sheet-metal construction, piston engines, conventional assemblies, and replaceable components are compatible with manufacturing methods used for military trucks, unlike aircraft, which rely extensively on specialized composite structures. Grid Aero estimates that 100,000 machines across the United States could manufacture Lifter components, potentially broadening the supplier base beyond established aerospace manufacturers. Following six to 12 months of anticipated testing, Oshkosh aims to establish a pilot line in late 2027 before expanding production according to orders. Manufacturing 500 cargo drones annually would require two completed aircraft per working day and 1,000 installed engines, generating $250 million to $1.5 billion in annual aircraft output across the proposed price range.

How Oshkosh and Grid Aero plan to mass-produce the Lifter cargo drone

At 1,000 aircraft annually, production would increase to four aircraft daily and 2,000 engines, excluding spares, but no funded production quantity or binding delivery schedule has been announced. Grid Aero developed the Lifter Lite with an initial team of approximately 14 employees, including engineers from Xwing, Joby Aviation, and Northrop Grumman, supported by $6 million in seed financing, AFWERX Phase II funding, and a $20 million Series A announced on January 26, 2026. The cargo drone combines two piston engines, a rugged landing gear, autonomous flight controls, metal construction, and a cargo compartment designed without the space requirements of a crewed cockpit. Its proposed 2,000-lb payload represents 4.76% of the C-130J Super Hercules' 42,000-lb maximum payload, meaning 21 fully loaded Lifter Lite flights would transport the same cargo mass as one maximum-payload C-130J sortie.

Other Lifter configurations target 1,000 to 8,000 lb (454 to 3,629 kg), with longer-range concepts extending toward 4,000 nautical miles (7,408 km), although maximum payload and maximum range have not been demonstrated together. A proposed cargo area of 450 sq ft (41.8 m²) and field assembly within 12 hours by two personnel are intended to further support expeditionary operations. Cargo-door dimensions, pallet compatibility, cruise speed, takeoff distance, fuel consumption, and dispatch reliability remain undisclosed as of November 9, 2026. The principal military logistical requirement that the Lifter Lite could address arises from the U.S. Air Force's Agile Combat Employment (ACE) concept, which distributes combat aircraft and maintenance personnel across multiple airfields to reduce vulnerability to attacks against concentrated bases.

Why the U.S. Air Force could use Lifter drones to resupply dispersed airbases

For instance, Resolute Force Pacific 2025 involved more than 400 aircraft, 12,000 personnel, and 50 operating locations across an exercise area extending 6,000 miles east to west and 4,000 miles north to south. Dispersing 24 fighters among six locations instead of one, however, creates six separate requirements for spare parts, specialized tools, communications equipment, and consumables, meaning an unavailable component can prevent an otherwise serviceable aircraft from flying. Guam lies 1,230 nautical miles (2,278 km) from Okinawa and 1,370 nautical miles (2,537 km) from Manila, which is within the Lifter Lite's proposed 2,000-nautical-mile one-way range. The drone could therefore be relevant for high-priority cargo whose delivery can restore aircraft availability, including replacement avionics, radar modules, communications equipment, specialized tools, medical supplies, and selected munitions between locations possessing suitable runways.

Its capacity would be less relevant for bulk fuel transportation: at 6.7 lb per U.S. gallon, 2,000 lb of JP-8 corresponds to 298 gallons (1,128 liters), excluding containers, which is insufficient for substantial fighter aircraft refueling requirements. The Lifter's proposed acquisition cost would also permit a different approach to aircraft losses than conventional crewed airlift, although it remains a reusable transport rather than a disposable drone. A fleet conducting 100 sorties daily would generate 3,000 sorties monthly; at hypothetical loss probabilities of 0.1%, 0.5%, and 1% per sortie, expected losses would reach three, 15, and 30 aircraft, respectively. At 3% and 5%, monthly losses would increase to 90 and 150 aircraft, assuming sufficient replacements to maintain sortie generation. With aircraft costing $1 million each, replacing 30 losses would require $30 million, while 90 would cost $90 million, excluding lost cargo, spare parts, and transportation into theater.

Could low-cost cargo drones sustain military deliveries despite aircraft losses?

A production line manufacturing 500 aircraft annually would deliver 41.7 monthly, sufficient to replace losses under the 1% scenario but insufficient under the 3% scenario. Even 1,000 aircraft annually would provide only 83.3 monthly replacements, below the 90 required at 3% attrition. The economic advantage would therefore depend on maintaining production above sustained losses while preserving aircraft availability and achieving a competitive cost per successfully delivered ton-mile. Losses on loaded outbound flights would additionally destroy cargo, whereas losses on empty return flights would primarily reduce subsequent transport capacity. In parallel, the U.S. military is evaluating several competing approaches to autonomous cargo transportation. Reliable Robotics is developing autonomous capabilities for the Cessna 208B Grand Caravan, with a cargo capacity in the 3,000-to-3,500-lb class and a $17.4 million U.S. Air Force agreement awarded in 2025.

Xwing demonstrated autonomous cargo movements between airfields separated by approximately 400 miles during Agile Flag 2024, while Textron Aviation and Merlin are pursuing an autonomous Cessna 408 SkyCourier capable of carrying 6,000 lb, three times the Lifter Lite's proposed payload. At the smaller end, the U.S. Marine Corps will conduct a Tactical Resupply Unmanned Aircraft System (TRUAS) Increment II demonstration in Huntsville from January 25 to February 5, 2027, requiring the delivery of 100 lb over 40 nautical miles with a return flight, or 150 lb over 10 nautical miles, at a minimum speed of 50 knots without catapult or arresting equipment. Grid Aero was also among seven companies selected in September 2026 for the U.S. Air Force's Massed Modular Aircraft (MMA) competition, which specifies a 2,800-lb payload, 2,300-nautical-mile combat radius, speed exceeding 200 knots, and runways no longer than 6,000 ft to replace the MQ-9A Reaper.

How China's expanding cargo drone programs compare with U.S. developments

China, for its part, is pursuing several autonomous cargo aircraft programs through AVIC, Xi'an Aircraft Industry Group, Norinco, and other manufacturers, with designs covering regional freight transportation and heavier logistics requirements. The Tianma-1000 completed its first flight in January 2026 and targets a 1,000-kg payload, 1,800-km range, 8,000-m service ceiling, and takeoff and landing distances below 200 m, with autonomous route management and configurations for cargo, communications relay, and reconnaissance. On April 15, 2026, AVIC's HH-200 completed a 22-minute inaugural flight at Pucheng, targeting a 2,360-km range, 12-to-18-m³ cargo compartment, 500-m minimum runway, and operation between -40°C and +50°C. Other projects include the Changying-8, targeting 3.5 metric tons over 3,000 km, alongside the TP1000, the W5000, and the larger Jiutian SS-UAV.

China's established aerospace factories, domestic propulsion and avionics suppliers, and extensive UAV manufacturing chains support parallel development, while commercial demand for regional freight and remote-area transportation increasingly provides an additional market beyond military procurement. For the People's Liberation Army, these cargo drones could connect mainland facilities with selected South China Sea installations, while 200-to-500-m runway requirements would permit access to smaller airfields, subject to runway condition, payload, and fuel availability. The resulting industrial competition between China and the U.S. therefore concerns not only aircraft payload and range, but also the ability to manufacture sufficient numbers, sustain repeated deliveries, and replace losses during prolonged operations across the Western Pacific.
