Development of TPM-1 will continue for a couple of years though to keep stocks up-to-date and certified with current DDS protocols.
One new TPM-1 development is the Canister-TPM Revolver (CTR) which has been developed by a third-party company for the DDS. Working like the cylinder on a revolver handgun CTR contains 6 TPM-1s in it's cylinder allowing for much greater firepower for auxiliary ships (and of course helping to reduce the TPM-1 stockpile faster!) CTR is currently being tested on a Provider transport and may enter service next year.
