The Velocity ILU, also known as Type 37 Unification, has been scheduled for next year by the DDS Commander. The Orchid said that there were not sufficient funds to carry out the ILU this year because of on-going upgrades to other types and new construction.
The ILU will unify the Type 37A and B to a similar standard to the Solaris 37C destroyers. This new Velocity 37D standard will have an improved engine, Z6 cannon, TPM-2 launcher and a number of other improvements.
