Aatmanirbhar Bharat: MoD inks Rs 449 crore contract for 20 Enhanced Capability Global Navigation Satellite System Jammers for Indian Navy

1. At a Glance

Ministry of Defence (MoD) signed a Rs 449 crore contract with Accord Software and Systems Pvt Ltd (ASSPL), Bengaluru for 20 Enhanced Capability GNSS (ECGNSS) Jammers for the Indian Navy [S1].
Procurement under Buy (Indian-IDDM) category with minimum 75% indigenous content — exemplar of Aatmanirbhar Bharat in defence electronic warfare (EW) [S1][S2].
UPSC-relevant intersection of GS-III (Internal Security / Defence Indigenisation / S&T) and current affairs on India's EW capability build-up.

2. Why in the News

Contract inked on 10 June 2026 in New Delhi in the presence of Defence Secretary Shri Rajesh Kumar Singh [S1].

3. Background & Evolution

DAP 2020 (Defence Acquisition Procedure) effective 1 October 2020 accorded top priority to the Buy (Indian-IDDM) category [S2].
IDDM = Indigenously Designed, Developed and Manufactured; reserved for Indian vendors with FDI ≤ 49% and resident Indian ownership/control [S2].
Series of Navy-IDDM contracts has accelerated: Sarang ESM (BEL), Lynx-U2 FCS, EON-51, MRSAM (BDL), NMDA (BEL) — ECGNSS Jammers extend this list into GNSS denial / spoofing EW segment [S3].

4. Core Static Facts

Contract value: Rs 449 crore [S1].
Quantity: 20 ECGNSS Jammer systems [S1].
Vendor: Accord Software & Systems Pvt Ltd (ASSPL), Bengaluru [S1].
End-user: Indian Navy (ship platforms) [S1].
Category: Buy (Indian-IDDM) [S1].
Indigenous content: minimum 75% [S1].
Signed in presence of: Defence Secretary Rajesh Kumar Singh, 10 June 2026 [S1].
Parent Ministry: Ministry of Defence; procurement governed by DAP 2020 [S2].

5. Multi-Dimensional Analysis

Scientific / Technological - GNSS = Global Navigation Satellite System — umbrella for GPS (US), GLONASS (Russia), Galileo (EU), BeiDou (China), NavIC (India) [S1]. - Jammer degrades adversary GNSS receiver's signal acquisition & tracking, plus deceptive jamming/spoofing (false signal injection to mislead enemy PNT — position-navigation-timing) [S1]. - Belongs to Electronic Warfare (EW) — Electronic Attack sub-domain.

Strategic / Geopolitical - Counters adversary precision-guided munitions, UAVs, and missiles that rely on GNSS — relevant given PLA Navy expansion in IOR and Pakistan's GPS-aided systems. - Strengthens sea-denial posture by neutralising hostile GNSS-dependent ISR.

Economic - 75% indigenous content routes value-add to domestic EW ecosystem (Bengaluru-based ASSPL) — supports defence exports target and import substitution [S1][S2].

Administrative / Governance - IDDM route bypasses lengthy global RFP; aligns with Positive Indigenisation Lists of MoD. - Reinforces DPSU + private sector parallel sourcing.

6. Recent Developments (last 12-18 months)

10 Jun 2026 — ECGNSS Jammer contract signed [S1].
Prior IDDM Navy contracts: MRSAM with BDL (Rs 2,960 cr), NMDA with BEL, EON-51 with BEL (Rs 642 cr) — pattern of accelerating IDDM deals [S3].
DAP 2020 periodically amended to deepen Aatmanirbharta in defence [S2].

7. Prelims Hooks

ECGNSS Jammer contract value: Rs 449 crore [S1].
Number of systems: 20 [S1].
Vendor: Accord Software and Systems Pvt Ltd, Bengaluru [S1].
Procurement category: Buy (Indian-IDDM) under DAP 2020 [S1][S2].
Minimum indigenous content: 75% [S1].
End-user: Indian Navy (not Army/Air Force) [S1].
Two functional capabilities: (a) degrade GNSS signal acquisition/tracking; (b) spoofing/deceptive jamming [S1].
DAP 2020 effective date: 1 October 2020 [S2].
IDDM vendor FDI cap: ≤ 49% [S2].
India's own GNSS: NavIC by ISRO (contextual contrast).
Signed by Defence Secretary Rajesh Kumar Singh [S1].

8. Mains Relevance

GS-III — Security: "Various Security Forces & Agencies and their mandate", "Role of external state actors in creating challenges to internal security"; S&T: "Indigenisation of technology and developing new technology"; "Achievements of Indians in S&T".
Possible stems: 1. "Discuss the strategic significance of indigenous Electronic Warfare capability acquisition for the Indian Navy in the context of the Indo-Pacific." 2. "Examine how the Buy (Indian-IDDM) category under DAP 2020 has reshaped defence procurement. Illustrate with recent contracts." 3. "GNSS denial and spoofing are emerging as decisive tools of modern naval warfare. Comment."

10. Common Errors / Trap Areas

GNSS ≠ GPS: GPS is one constellation within GNSS; do not equate.
Vendor: Accord Software & Systems is a private Bengaluru firm — not a DPSU like BEL/BDL.
Category: It is Buy (Indian-IDDM), not "Make-I" or "Buy & Make (Indian)".
Indigenous content: minimum 75%, not 50% or 60% (50% is the IDDM floor in some sub-cases; 75% applies here).
End-user is Navy only — not tri-services.
