Recognising the need to focus on support for the military variant, the Defender 4000, Britten-Norman formed a new Maintenance, Repair and Overhaul (MRO) subsidiary - BN Defence.

Located in a dedicated facility in Lee-on-Solent, the company provides full base maintenance support for the Defender 4000 and the government variants of the Islander.

The company‘s personnel have a wealth of experience in maintaining multiple current in-service aircraft types, ranging from light turbo props through to fast jets and large aircraft. Current services include maintenance, electrical manufacturing, avionics installation, and aircraft test & evaluation, and the company is expanding its MRO capabilities to include multiple military aircraft types. Through its close working relationship with Britten-Norman Aircraft, the company can also provide on site design capabilities to support its MRO and modification activities.

BN Defence operates under MAOS approval, MIL Part 145 approval. The Company is ISO 9000 accredited.
