The DDS have been upgrading older Type A transports in the HCS fleet with new engines and refurbishing them. 20 were originally destined for the upgrades of which 12 have now been completed. The HCS have signed a contract extension with DDS Upgrades to increase the number to 25 which will take the programme to the end of next year.
The upgrades are also now to include an improved navigational system though these are HCS built and will simply be fitted by the DDS.
