The Ferret-E UCV is now winding down in production for the DDS though will continue for export customers. Ferret-G, the version able to operate in atmospheres as well as space, is now coming to the end of it's test programme and is due to begin production early next year. The Dinos are finally going to purchase the type (they did not buy the E as they were waiting for the G, which they largely developed anyway) which will bring down the unit price.
The DDS will rebuild it's fleet of Es to G standard as the UCVs enter their refits over the next few years. Aerodynamically the E and G are virtually the same though the engine is new and the avionics are quite different. These will be replaced during the upgrades.
