The third generation of the TPM-2 missile has entered service with the DDS and all new production will switch to the model by the end of the year (thousands of As and Bs remain in service though and will be expended naturally). The TPM-2 Gamma has a number of improvements to enhance the weapon's effectiveness in the face of counter-measures by rival powers.
"The Two Gamma hits harder and hits faster." Sea Urchin, the Director of Technology, said at a media briefing to announce the launch. "We have developed a new improved seeker able to negate sensor spoofing and multi-layer shields. There is also provision for a larger warhead, though this means fitting a smaller fuel tank. This can be something officers in the field can decide as a trade-off. The Two Gamma has a new engine development that takes advantage of technology transfer from our Porquatian allies, the missile is now up to 20% faster." ECM has also been enhanced though Sea Urchin did not mention it.
The TPM-2 Gamma will be the basis of the whole TPM family for the next 2-3 years. Air and ground launched versions are expected in the next few months. It is compatible with existing launchers and the new VLS. The missile also debuts a new version nomenclature system, in development it was known as the 2C.
