The General Electric GE4 turbojet engine was designed in the late 1960s as the powerplant for the Boeing 2707 supersonic transport. The GE4 was a nine-stage, single-shaft, axial-flow turbojet based largely on the General Electric YJ93 which powered the North American XB-70 bomber. The GE4 was the most powerful engine of its era, producing 50,000 lbf (220 kN) dry, and 65,000 lbf (290 kN) with afterburner. The Boeing 2707 was cancelled in 1971, putting an end to further work on the GE4.

Fou concebut com a planta motriu per al transport supersònic . El GE4 era un turboreactor de nou etapes, un sol eix i flux axial basat principalment en el , el motor que impulsava el bombarder . El GE4 era el motor més potent del seu temps, amb un empenyiment de 220 kN en sec i 290 kN amb postcremador. La cancel·lació del Boeing 2707 el 1971 feu que també s'abandonés el GE4. (ca)

- ゼネラル・エレクトリック GE4 ターボジェットエンジンは1960年代末にボーイング2707 超音速旅客機の動力として設計された。GE4はノースアメリカンXB-70爆撃機のエンジンであるYJ93を原型とする9段単軸軸流式ターボジェットエンジンである。 GE4は当時最も強力なエンジンでアフターバーナーを使用せずに50,000 lbf (220 kN)の推力を生み出し、アフターバーナー使用時には 65,000 lbf (290 kN)の推力を生み出した ボーイング2707は1971年に中止され、それに伴い、GE4の開発も終了した。 (ja)
