An improved version of the air-launched version of TPM-1, the TPM-A3, has entered service with the DDS. This is still using the TPM-1 as it's base but is now using a customised version of the TPM-1D4 (the current production version). The DDS have been working on an air launched version of the TPM-2, the TPM-A-2X, but have decided to stay with -1 for now to help bring down the stockpiles. All -A3s will be re-used TPM-1 rounds. The DDSAF say they will switch to using the TPM-2 in the "next decade".
As for the -A3 is has all the enhancements of the latest missile with improved datalinking and terminal seeking systems. The -A3 also has a modified rocket booster with improved safety features.
Also announced is the first TPM-G battery which has been sited at DDS GHQ. The TPM-G is a ground launched version of the missile. It is using a slightly modified TPM-A as it's base with a much larger booster stage. TPM-G will be able to strike objects in LEO as well as targets in the atmosphere and form yet another layer of defense. The first battery is being trialled this year and further batteries may be built across the DDS and UNP if successful.
