First Tiltrotor Utility Aircraft to Replace Black Hawk Roles

United States Army於15日正式將新一代傾斜旋翼機MV-75定名為「夏延2型」（Cheyenne II），延續以美洲原住民族命名軍機的傳統，向Cheyenne族致敬，並象徵其勇武精神將延續至新世代戰場。

The United States Army officially named its next-generation tiltrotor aircraft MV-75 as “Cheyenne II,” continuing the tradition of honoring Native American tribes and symbolizing the warrior spirit carried into future battlefields.

陸軍首款傾斜旋翼機　性能大幅超越直升機

Army’s First Tiltrotor Platform with Superior Performance

該命名於Army Aviation Warfighting Summit 2026公布，經評估逾500個名稱後選定「夏延」，並成為繼AH-56 Cheyenne後，再度採用該名稱的軍機型號。

The designation was announced at the 2026 Army Aviation Warfighting Summit. After reviewing over 500 names, “Cheyenne” was selected, marking the second aircraft after the AH-56 Cheyenne to bear the name.

由Bell Textron研製的MV-75，「MV」代表「多任務垂直起飛」，「75」則象徵美國陸軍創立於1775年，並肩負接替UH-60 Black Hawk任務的角色。

Developed by Bell Textron, “MV” stands for Multi-Mission Vertical Takeoff, while “75” commemorates the Army’s founding in 1775. The aircraft is intended to take over missions currently performed by the UH-60 Black Hawk.

高速長程兼具　支援多元作戰任務

High Speed and Range Enable Multi-Mission Flexibility

MV-75具備傾斜旋翼設計，可兼顧直升機垂直起降與固定翼飛機高速巡航優勢，巡航速度達280節（約518公里／時）、作戰半徑約1480公里。

The MV-75’s tiltrotor design combines vertical takeoff capability with fixed-wing cruise efficiency, achieving speeds of up to 280 knots (518 km/h) and a combat radius of approximately 1,480 kilometers.

除4名機組人員外，該機可搭載14名士兵或約4.5噸酬載，執行兵力投射、後勤運輸、醫療後送等任務，並可結合無人機進行情監偵與打擊行動，展現高度任務彈性。

In addition to a four-person crew, the aircraft can carry 14 troops or 4.5 tons of payload, supporting missions such as troop transport, logistics, and medical evacuation, while also integrating with unmanned systems for ISR and strike operations.

尊重歷史文化　預計2027年開始交付

Honoring Heritage with Deliveries Starting in 2027

Bell Textron表示，儘管歷史上曾有衝突，但夏延族的勇氣與紀律深受尊重，並已獲族人同意使用名稱，象徵精神傳承。

Bell Textron noted that despite historical conflicts, the Cheyenne people’s courage and discipline are highly respected, and the naming was approved to honor that legacy.

目前量產型測試機正加緊製造，預計2027年開始交付101st Airborne Division，並於2028年正式部署服役，成為美軍未來空中機動戰力核心。

Production test aircraft are currently in development, with deliveries expected to begin in 2027 to the 101st Airborne Division, followed by full operational deployment in 2028 as a core element of future U.S. Army air mobility.
