Airbus Retires Iconic Beluga ST-4 After 30 Years of Service
Airbus has officially retired the Beluga ST-4 transport aircraft, closing the chapter on three decades of oversized cargo operations.
Airbus has officially grounded the Beluga ST-4, one of its distinctive whale-shaped Super Transporters, marking the end of a 30-year operational run that helped define how the aerospace giant moves large aircraft components across Europe and beyond. The retirement signals a generational shift in Airbus's heavy-lift logistics fleet.
The Beluga ST — short for Super Transporter — earned its nickname from its unmistakable bulbous fuselage, which was purpose-built to ferry oversized aircraft sections such as wings and fuselage barrels between Airbus manufacturing sites. The ST-4 was one of five such aircraft that formed the backbone of the company's component transport network for decades.

Airbus has been transitioning its outsized cargo operations to the newer BelugaXL, a larger and more capable successor that entered service in recent years and offers greater cargo volume than its predecessor. The phased retirement of the original Beluga ST fleet reflects the company's broader push to modernize and expand production capacity as it works to meet surging commercial aircraft demand.
The ST-4's retirement is more than a logistical footnote — it represents the end of an era for a fleet of aircraft that became cultural icons in the aviation world, regularly drawing crowds at airports wherever they landed. Aviation enthusiasts and industry observers have long celebrated the Beluga's unusual silhouette as one of the most recognizable shapes in the skies.
As Airbus accelerates output of its A320 family and wide-body jets, the BelugaXL fleet is expected to shoulder an increasing share of inter-site transport duties going forward. Continue reading at interestingengineering.
