Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether he has had discussions with his (a) German and (b) Dutch counterpart on longer exhausts in (a) CH-47 Chinook, (b) Puma, (c) Sea King and (d) Westland Wessex helicopters.

We have found no record of any discussions with Dutch or German counterparts regarding longer exhausts on Chinook and Puma aircraft. The German military does not operate Chinook nor Puma helicopters. The Netherlands does not operate Puma helicopters.

Due to their out of service dates of 2003 and 2018, no relevant information is held within Ministry of Defence relating to Sea King and Wessex helicopters; however, the Netherlands did not operate Sea King helicopters and neither country operated the Wessex.
