# Lufthansa AeroSHARK coating trial > Live situation record from CLSTR: https://clstr.news/situations/lufthansa-aeroshark-coating-trial > Updated: 2026-08-01T22:33:50.000Z. Sources: 5. Developments: 2. Lufthansa Technik began field testing its next‑generation AeroSHARK surface‑coating on an Airbus A319 operated by Lufthansa City Airlines. The aircraft, registered D‑ABGK and flying the Munich‑Hamburg short‑haul route, was fitted with about 70 transparent 20 × 20 cm film patches on the fuselage and engine cowlings. The trial, running until February 2027, aims to evaluate material durability, ease of cleaning and residue‑free removal, with a view to extending the coating to wings and tail surfaces. A follow‑up report added that the coating mimics shark‑skin riblets to cut aerodynamic drag, targeting roughly a 1 % reduction in fuel burn and CO₂ emissions per flight. Lufthansa’s long‑haul fleet already uses AeroSHARK on several Boeing 777 and a 747‑400, saving an estimated 19 tonnes of kerosene and 60 tonnes of CO₂ daily. The narrow‑body test therefore forms part of a broader effort to lower fuel consumption and meet environmental targets across the airline’s fleet. ## Timeline ### 2026-08-01: Lufthansa Technik tests AeroSHARK fuel‑saving coating on Airbus A319 narrow‑body jet Lufthansa Technik and Surventis are testing AeroSHARK coating on an Airbus A319, aiming for ~1% fuel and CO₂ savings, with trials running until Feb 2027. 3 sources. https://clstr.news/cluster/lufthansa-technik-tests-aeroshark-fuelsaving-coating-on-airbus-a319-narrowbody-jet ### 2026-07-30: Lufthansa Technik begins next‑generation AeroSHARK tests on A319 short‑haul jet Lufthansa Technik is testing next‑gen AeroSHARK fuel‑saving film on a Lufthansa City Airlines A319 between Munich and Hamburg, using 70 transparent patches to gather data for future wing and stabiliser use. 2 sources. https://clstr.news/cluster/lufthansa-technik-begins-nextgeneration-aeroshark-tests-on-a319-shorthaul-jet --- Cite as: Lufthansa AeroSHARK coating trial.
