On 20 June 2022, the fourth and last General Atomics AeroTec Systems Do228-212NG, serial 314-04 and test registration D-CAEP (construction number 8327), for the Bangladesh Navy was seen test flying from Oberpfaffenhofen and visiting Braunschweig.
This probably means the delivery will commence shortly. The future S3 registration will most probably be S3-VHT.
The Do228s are operated by the Naval Aviation Wing and are based at Zahurul-Haque Air Base, which is part of Chittagong/M.A. Hannan International Airport. The first two Do228s were already delivered in 2013 and number three was delivered in October 2021.
