Design refinements included engine improvements and afterburner capability. The Tunnan introduced aerodynamic ideas influencing future Saab jets. It featured advanced safety features like a pressurized cockpit and ejection seat, enhancing pilot safety at high altitudes.

The Tunnan saw combat as part of United Nations peacekeeping missions in 1961-1962 without any aircraft losses despite heavy ground fire. Austria became another operator in 1961-1962, naming it 'Tonne.' The Tunnan remained in Austrian service until 1972.

Pilots praised its maneuverability and firepower with four Hispano cannons and various bomb configurations. The J-29F variant added Sidewinder missiles in 1963, enhancing its interceptor capabilities.

Production spanned over a decade with variants including J-29A, J-29B, A-29B, S-29C, and J-29E models. In total, 661 units were produced between 1950 and 1956—the largest production run of any Saab aircraft to date.

The adoption of guided missile technology led to changes passed on to subsequent Saab fighters like the Draken. Although retired from active service by 1965, some Tunnans were used for target towing until 1974.

Saab credits lessons learned from designing and building the J-29 as foundational for later innovations like the Lansen and Viggen models. This success demonstrated that domestic designs could compete internationally.

By the mid-1960s, evolving defense priorities led to phasing out most Tunnan variants. Many have been preserved in museums or flight-worthy collections as reminders of their era's significance.

Swedish aerospace history acknowledges the Tunnan's role in transforming domestic industry into a respected name for cutting-edge designs. Its record-setting performance cemented its status as an icon of early jet aviation—a testament to Swedish engineering excellence.
