Apollo Micro Systems Limited has secured a Make-II Prototype Sanction Order from the Indian Air Force to design and develop the IPREK guidance system. The project converts existing 500 kg air-dropped bombs into long-range precision-guided smart munitions using India's indigenous NavIC satellite navigation constellation.
HYDERABAD/NEW DELHI — Hyderabad-based defense electronics firm Apollo Micro Systems Limited (NSE: APOLLO, BSE: 540879) has been awarded a Make-II Prototype Sanction Order (PSO) by the Indian Air Force and Ministry of Defence to develop the Indigenised Precision Roll-Out Kit (IPREK). Disclosed in regulatory filings on Tuesday, July 28, 2026, the award empanels the company as a Prime Original Equipment Manufacturer (OEM) tasked with designing, developing, and demonstrating a prototype guidance and navigation kit for 500 kg conventional air-dropped bombs.
The IPREK system is engineered to transform India's vast existing stock of conventional unguided bombs into high-precision, long-range standoff smart weapons at a fraction of the cost of acquiring imported guided munitions. By integrating India's indigenous Navigation with Indian Constellation (NavIC) satellite positioning technology, the project reinforces national defense self-reliance under the Atmanirbhar Bharat initiative.
Converting Conventional Munitions into Standoff Precision Weapons
The primary technical goal of the IPREK initiative is to retrofit standard 500 kg iron bombs with advanced control surfaces, aerodynamic wing units, and satellite-guided navigation packages. Once fitted with the kit, aircraft can release these converted smart weapons from distances between 80 and 100 kilometers away from the intended target, allowing launch platforms to remain well outside the range of enemy air defense systems.
According to technical specifications outlined in corporate announcements, the IPREK guidance kit aims to deliver a Circular Error Probable (CEP) of less than 3 meters. This high level of accuracy ensures pinpoint terminal targeting against heavily fortified ground installations, command infrastructure, and logistics nodes.
Crucially, the system utilizes NavIC (IRNSS) satellite signals at its core. This indigenous satellite architecture prevents vulnerability to foreign GPS signal jamming or spoofing during operational deployments, providing sovereign positioning and navigation integrity for IAF strike missions.
Financial Structure Under the Make-II Defense Framework
The award has been granted under the Ministry of Defence’s Make-II procurement category. Under this indigenization policy, private sector defense firms bear zero financial liability or development cost burdens for the government during the initial design and prototype testing phase.
In return, the Ministry of Defence provides a structured commitment for series procurement upon successful flight demonstration and field trials of the prototype. This framework allows defense manufacturers to secure long-term production contracts while enabling the armed forces to modernize weapon inventories efficiently.
Industry analysts note that this empanelment transitions Apollo Micro Systems from a component and sub-assembly supplier into a full-stack system integrator capable of delivering complete weapon-class platforms. The precision-guided munition market represents one of the highest-value segments within Indian defense manufacturing, carrying significant technological entry barriers.
Expansion Across Air Force and Naval Platforms
The Indian Air Force order follows a similar high-profile defense milestone achieved by Apollo Micro Systems earlier in the month. On July 22, 2026, the company secured a Make-II Prototype Sanction Order from the Indian Navy for the design and development of SAVIOR-ASW, an autonomous semi-submersible platform built for persistent anti-submarine warfare surveillance.
To support its expanding role in high-precision weaponry and explosives integration, Apollo Micro Systems recently completed strategic corporate expansions, including the acquisition of a controlling stake in Premier Explosives. Combined with new manufacturing infrastructure in Telangana, the firm has built backward-integrated capabilities covering electronics, guidance kits, warhead integration, and rocket propellants.

Frequently Asked Questions (FAQ)
What is the IPREK project awarded to Apollo Micro Systems?
IPREK (Indigenised Precision Roll-Out Kit) is a guidance and navigation system designed to convert standard 500 kg conventional bombs into high-precision, standoff smart weapons for the Indian Air Force.
How does the IPREK guidance kit improve bomb accuracy?
The kit integrates aerodynamic control fins and guidance electronics linked to India's NavIC satellite navigation system, allowing bombs released from 80–100 km away to hit targets within 3 meters.
What is the Make-II framework used in this defense contract?
Under the Make-II category, private companies design and fund the prototype development phase independently, and the Government of India commits to purchasing the finalized weapon system once flight tests are successfully proven.
Why is NavIC integration significant for Indian smart bombs?
NavIC provides an independent, sovereign satellite navigation signal, ensuring that Indian air-launched precision weapons remain effective and immune to foreign GPS restrictions or electronic interference during conflict.
