The final 4 of the original Coril 79A fleet are to be fully refurbished and upgraded which should allow them to operate until around 2120. The upgrades will take place later this year and will include reengining with the CFM WSN-865J powerplant used in the next generation Coril 79B. The ships will also be fitted with specialist sensor and communications equipment, improved accommodation, improved airlocking facilities and a triage facility for their new role supporting DDS special forces.
With the new engine the ships will be speed boosted to 200c which is the maximum the frame is able to maintain, this is less than the 250c the Coril 79B can reach but is not considered a problem as the engine will be lower-rated to reduce emissions. Its is thought the ships will be fitted with extensive cloaking technologies. When asked why the DDS was re-using old ships instead of just building 4 new Coril 79Bs the reasons were cost, a refurbished older Coril is cheaper than a new one and also the new Coril's internal space is reduced (as the ship has been designed to be stronger for higher speeds) so was less suitable for the SpecOps needs.
The first upgrades will take place in the late Summer and all will be completed by the end of the year.
