Re: Indian Missiles News and Discussions - May 2017

PTAE-7 engine was made with re-use in mind in fact it has been tested for splash down in sea , recovery and then re-use so from material pov it was not conceived for one time use per se , all in all there is room to make it cheaper but that is probably not a priority item.
