UPPCS Science & Technology Gap Sheet: Defence platforms, bodies and exercises.
UPPCS has asked 18 of these. 8 have not been asked yet. Lock the first list, then read the second: it holds what UPPCS has not used yet.
First, the concept
Separate the platform from its weapon: an aircraft can carry a missile, and a submarine can carry a ballistic missile. Indigenous construction and foreign design assistance can coexist.
Defence bodies have different roles in research, production and operation. Pair exercise names with the partner country and service.
