Five Fighter Jets Still in Production Decades After Debut
From Russian-designed airframes to American veterans, several military aircraft production lines continue operating more than three decades after their prototypes first took flight, with one Western design now being built 54 years after its maiden sortie.

Several fighter jet production lines remain active decades after their initial prototypes flew, according to a recent analysis of current manufacturing activity. The longevity spans from a 37-year-old Russian-designed platform recently revived in India to an American aircraft that has maintained production for over half a century.
The Sukhoi Su-30 family represents one such enduring design, with roots in a prototype that first flew in late December 1989. India's Hindustan Aeronautics developed a licensed variant known as the Su-30MKI, incorporating distinctive modifications including canards, thrust-vectoring engines, and an international avionics package combining Russian, Indian, Israeli, and French systems. The Nashik production facility manufactured 222 aircraft before shutting down in 2020-2021 after completing its contract.
That hiatus proved temporary. In December 2024, HAL secured a contract valued at approximately 11,000 crore rupees—roughly $1.3 billion—to manufacture 12 replacement Su-30MKIs for aircraft lost in operational accidents, according to reporting from The Economic Times. The renewed production line is expected to deliver its first jet during 2027-2028, with all dozen aircraft scheduled for completion by 2029. This new batch will reportedly feature more than 50 percent domestically-sourced Indian components, marking a significant increase in local content compared to earlier production runs.
The Su-30 production restart illustrates an important distinction among long-running fighter programs: not all represent continuous manufacturing. Some lines, like Nashik's, have experienced complete shutdowns before reactivating under new contracts, differentiating them from facilities that have maintained uninterrupted output since their aircraft's introduction.
The analysis identified five current production programs, spanning manufacturers including Lockheed Martin, Dassault Aviation, Saab, Hindustan Aeronautics, and Boeing. The longest-running Western fighter design reportedly continues assembly in St. Louis after 54 years, claiming the distinction of the oldest continuously-produced combat aircraft still rolling off assembly lines in the Western world.
