All Nippon Airways (ANA) welcomed another marine-life-inspired aircraft to its fleet: Its first Boeing 777 equipped with AeroSHARK. This revolutionary surface technology is inspired by shark skin, reduces drag, and enhances fuel efficiency. ANA is the first individual airline to operate both 777 passenger and freighter variants with this innovation.

The first modified Boeing 777F (JA771F) began scheduled cargo flights, with plans to extend the AeroSHARK technology to a passenger aircraft (JA796A) by next Spring, furthering ANA’s commitment to investment in fuel efficient technologies that reduce emissions.
AeroSHARK, a joint development by Lufthansa Technik and BASF, is a functional surface film inspired by the drag-reducing structure of sharkskin. The film features ribs around 50 micrometers in size, called riblets. Closely guided by Lufthansa Technik, ANA’s MRO partner has recently applied several hundreds of square meters of these riblet films to the fuselage of JA771F, which re-entered commercial service today with the first AeroSHARK-optimized flight from Tokyo-Narita to Chicago-O’Hare.
Although the riblet modification is almost invisible, it is expected to deliver significant fuel and emissions savings. The contracted Boeing 777F and 777-300ER aircraft will have nearly the entire fuselage covered with the sharkskin-inspired film, resulting in estimated annual savings of approximately 250 metric tons of fuel and 800 metric tons of CO2 for each aircraft.
As ANA begins operations with two Boeing 777 equipped with riblet films, the airline will validate the effectiveness of this technology in ANA’s daily operation, with plans to expand its use across other aircraft of the same type. This initiative is part of the ANA Group’s medium- to long-term environmental strategy, which includes the broader “ANA Future Promise” initiative aimed at realizing a sustainable society and promoting ESG management.
Lufthansa Technik currently holds Supplemental Type Certificates (STCs) for the AeroSHARK modification of various types of Boeing 777, which is now being adopted by various airlines across the globe. Approximately 20 long-haul aircraft are already operating with the technology in worldwide service, and this number is growing steadily.
BASF and Lufthansa Technik moreover remain committed to further developing AeroSHARK to help more airlines achieve their sustainability goals. Current efforts include expanding approvals to additional aircraft types and covering larger surface areas. Initial model calculations suggest that sharkskin technology could potentially reduce CO2 emissions by up to three percent in its maximum expansion stage.
