Japan’s ShinMaywa US-2 amphibious aircraft has attracted growing interest from the US military, which has incorporated the platform into joint training activities focused on strengthening maritime search-and-rescue missions and logistics support for island operations. Operated by the Japan Maritime Self-Defense Force, the US-2 is widely recognized as one of the world’s most capable amphibious aircraft.
With an estimated price tag of around $160 million, the aircraft is engineered for operations in harsh maritime conditions where conventional aircraft face significant limitations. Its ability to land and take off from rough seas with waves reaching 3 meters in height sets it apart from other active seaplanes.
A key element of the aircraft’s performance is its advanced STOL capability. A dedicated fifth turbine engine channels airflow over the flaps and wings, improving lift generation, preventing stalls, and enabling operations at exceptionally low speeds of approximately 50 knots.
The US-2 incorporates a digital glass cockpit, fly-by-wire flight controls, and a pressurized cabin that supports long-range missions at higher altitudes. Powered by four Rolls-Royce AE2100 turboprop engines, the aircraft can reach speeds exceeding 300 knots while offering an operational range of about 2,800 nautical miles.
India and Japan have long explored the possibility of a US-2 procurement programme, with Indian requirements estimated at 12 to 18 aircraft for naval and coast guard missions. The proposed acquisition was valued between $1.35 billion and $1.65 billion.
The Andaman and Nicobar Islands were identified as a potential operating base for the aircraft, enabling India to strengthen maritime domain awareness across the Bay of Bengal and expand its operational reach toward the Malacca Strait and the South China Sea.
Despite efforts by Japan to make the programme more attractive—including reducing the unit price to around $113 million and offering local production opportunities under the “Make in India” framework through partnerships involving companies such as the Mahindra Group—the deal remains unresolved. Progress has been slowed by shifting budget priorities within the Indian Navy and the challenges associated with India’s defense acquisition procedures.
