Examine how the Buy (Indian-IDDM) category advances Aatmanirbhar Bharat in defence. What challenges persist?

Buy (Indian-IDDM) — Indigenously Designed, Developed and Manufactured — is the highest-priority procurement category under the Defence Acquisition Procedure (DAP) 2020, reserving orders for weapons designed and built in India. The September 2026 contract for 160 SAT-SAAW glide bombs shows both its promise and its limits.

How IDDM advances self-reliance

• Converts indigenous R&D into production orders: the ₹810.79 crore MoD–Bharat Dynamics contract for 160 SAT-SAAW for the IAF was signed under Buy (Indian-IDDM) [1].
• Sustains the DRDO–PSU pipeline: SAAW was designed by Research Centre Imarat (DRDO), integrated by HAL, and now produced by a defence PSU — design, integration and manufacture all domestic [2][1].
• Builds capability, not just components: the weapon's 100-km stand-off range lets aircraft strike airfields outside dense air-defence envelopes [2].
• Mandates indigenous content: DAP was amended in November 2023 to require at least 50% indigenous content across categories, and five positive indigenisation lists cover 5,012 items, of which 61% stand indigenised [3].

Challenges that persist

• Test-to-induction lag: PIB records SAAW flight tests from 2021, yet the order came years later. CAG found 119 of 178 DRDO projects missed original timelines; the Standing Committee on Defence (2023) found 23 of 55 projects delayed, some closed as technology turned obsolete [3][4][2].
• Thin research funding: R&D's share of the defence budget fell from 4.7% (2014-15) to 3.9% (BE 2025-26) [3].
• Residual dependence: a 50% floor leaves half the value importable; NavIC covers only ~1,500 km beyond India's boundary, which is why an electro-optical seeker backs up satellite guidance [5][2].
• Absorption gap: India remained the world's largest arms importer (2013-23), and the IAF holds 31 of 42 authorised fighter squadrons [3].

IDDM has shifted indigenisation from assembly to design ownership, but self-reliance must be measured by time-to-induction, not successful tests. Strengthening DPSU in-house R&D, compressing the 19–26-month acquisition cycle, and operationalising the 15th Finance Commission's non-lapsable modernisation fund can make Aatmanirbhar Bharat a capability outcome, not merely a procurement label [3][4].
