LATAM Extends AeroSHARK Installation to Entire 777-300ER Fleet

LATAM Extends AeroSHARK Installation to Entire 777-300ER Fleet
LATAM Airlines Group has announced plans to equip its entire fleet of Boeing 777-300ER aircraft with AeroSHARK, an innovative fuel-saving riblet film developed jointly by Lufthansa Technik and BASF. This move underscores the airline’s ongoing commitment to enhancing operational efficiency and advancing sustainability goals. The decision follows a successful initial rollout on several aircraft, where AeroSHARK demonstrated both technical reliability and economic benefits, including a notable 1% reduction in fuel consumption and associated emissions.
Expanding a Proven Technology
LATAM was the first airline outside the Lufthansa Group to adopt AeroSHARK, initially applying the sharkskin-inspired film to a 777-300ER in December 2023. This early, discreet deployment allowed the airline to rigorously assess the technology’s performance under everyday operational conditions. After nearly a year of service confirmed the anticipated fuel savings, LATAM expanded its order in 2024, committing to retrofit all 10 of its 777-300ERs. The final installation is scheduled for completion by 2027, positioning LATAM as only the second airline worldwide to operate an entire subfleet equipped with this advanced riblet technology.
Nicolas Seitz, head of fleet and projects at LATAM Airlines Group, highlighted the strategic importance of the initiative: “Expanding the use of AeroSHARK across our entire Boeing 777-300ER fleet is a clear example of how LATAM combines innovation, operational efficiency and sustainability in very concrete actions. The proven results achieved with the first aircraft give us the confidence to scale this solution, reducing fuel consumption and emissions while maintaining the highest operational standards. This initiative is fully aligned with our long-term strategy to operate a more efficient and sustainable fleet.”
Technical and Environmental Impact
AeroSHARK is a surface film engineered to replicate the flow-optimized structure of sharkskin. Its microscopic riblets, approximately 50 micrometres in size, are aligned with the airflow to reduce aerodynamic drag. On the 777-300ER, the film covers nearly the entire fuselage and engine nacelles, encompassing roughly 950 square meters. Once fully deployed, the technology is expected to achieve a 1% drag reduction, translating into annual savings of up to 4,000 metric tonnes of jet fuel and a reduction of 12,000 metric tonnes of CO₂ emissions. This environmental benefit is equivalent to the emissions from approximately 56 scheduled São Paulo–Miami flights.
LATAM’s proactive adoption of AeroSHARK places the airline at the forefront of fuel efficiency initiatives among global carriers. As the aviation industry faces increasing pressure to reduce its carbon footprint, LATAM’s commitment may encourage competitors to accelerate the adoption of similar aerodynamic technologies. While Airbus and Boeing continue to dominate the commercial aircraft market, LATAM’s advancements in operational efficiency establish a benchmark that others may seek to emulate. Meanwhile, other industry players are focusing on different priorities: Singapore Airlines is enhancing maintenance reliability through an extended contract with Collins Aerospace for its 777 fleet, and Embraer is concentrating on E2 sales rather than new airliner development, potentially giving LATAM a competitive advantage in sustainability efforts.
Lufthansa Technik and BASF are also expanding AeroSHARK’s certification beyond the Boeing 777-200ER, 777-300ER, 777F, and 747-400 models, with plans to introduce the technology on the Airbus A330ceo by 2026. Early projections suggest that further surface coverage could unlock fuel savings of 2% to 3% in the future, highlighting the growing significance of aerodynamic efficiency in commercial aviation.
