The P-75(I) submarines will be indigenously constructed through the strategic partnership model (SPM) of procurement, which aims to revitalise the defence industrial ecosystem and progressively build indigenous capabilities in the private sector to design, develop and manufacture complex weapon systems for the future needs of armed forces.

Kishore Kumar Khera replies: Military aviation, like any other technology-intensive field, continuously evolves. Although a classic definition of various generations of combat aircraft does not exist but based on the core capabilities, it is broadly classified.
