Prelims Strategy

To ace DRDO-related questions in Prelims, a factual and concept-driven approach is essential. Begin by mastering the absolute basics: 'DRDO establishment year and founder' (1958, amalgamation of TDEs, DTDP, DSO), its administrative ministry (Ministry of Defence), and the current Chairman ('DRDO chairman current 2024').

Next, focus on its flagship projects and 'DRDO major missile projects list'. Memorize the names and key characteristics of missile series like Agni (range, type), Prithvi, BrahMos (collaboration), Akash, Nag, and Pralay.

Understand the significance of projects like Tejas ('DRDO Tejas fighter aircraft development') and Arjun MBT. Pay close attention to 'DRDO achievements for UPSC' such as Mission Shakti (ASAT test) and its implications.

A crucial area is the 'DRDO laboratories list'; while memorizing all 50+ labs is impractical, know the major ones (e.g., DRDL, RCI, ADE, ARDE, CVRDE) and their primary functions. Current affairs are vital: track 'DRDO recent achievements 2023-24', new missile tests, significant inductions, and budget allocations ('DRDO budget allocation 2024').

Practice differentiating DRDO from ISRO and DAE using a 'DRDO vs ISRO comparison table' to avoid common traps. Use mnemonics and flashcards for quick recall of facts, numbers, and dates. Vyyuha recommends creating a timeline of major DRDO milestones.
