Aero India 2025-PGMs and development in India

"Fast is fine, accuracy is everything," said Wyatt Earp (an American lawman in the American West). The deadly package of speed, accuracy, and agility is precision guided munitions (PGMs), which have proven their mettle since WW2 and are still being used in various forms, revolutionising warfare! So, integrating these into countries' arsenals is not just beneficial; it is essential for future readiness. PGMs are smart munitions that can carry out precision strikes on intended targets, minimising collateral damage using an onboard guidance system.

 

Understanding PGMs

 

Historically, armed conflicts around the globe used large amounts of unguided bombs to take on enemy targets. However, as technology progressed, the introduction of PGMs changed the game. These munitions use various guidance systems like GPS, laser or infrared to hit targets with pinpoint accuracy, thereby significantly increasing the probability of a successful strike while minimising unintended effects on surrounding areas. This also reduces the number of ordnance a platform needs to carry to destroy a target.

 

The strategic implementation of PGMs offers numerous tactical advantages. Foremost among these is the ability to engage high value critical targets without the need for large scale deployments. This is particularly relevant for countries like India, which faces a multi-front security environment involving both conventional and asymmetric threats.

 

PGM development in India

 

The Country's premier defence research organisation, the Defence Research and Development Organisation (DRDO), has made significant strides in developing PGMs. Various projects have been initiated to fulfil the needs of the Indian Air Force. Recently private players have shown great interest in this field, coming up with solutions for drone based PGM, guidance kits and the production of systems developed by DRDO.

 

Furthermore, PGMs from other nations, such as the United States, Russia, Israel and France have bolstered India’s capabilities. One such significant example is the usage of the "Spice-2000" guided bomb developed by Rafael Advanced System, Israel was used by IAF in the Balakot airstrike.

 

Key projects

 

-Sudharshan, a 450 kg laser guide bomb developed by DRDO labs. IAF inducted it in a limited quantity.

-PGHSLD is an add-on GPS/INS guidance kit for High-Speed Low Drag (HSLD) bombs. Currently, the kit can be retrofitted to the existing unguided 450 kg bomb available with IAF inventory to convert it to a smart guided bomb. This increases the forward throw of the bomb from 10 km (unguided bomb) to 30 km when released from 10 km altitude at 0.85 Mach with an accuracy of 30m (only GPS-INS) and 3 m (with laser seeker).

-Gaurav, a 1000 kg glide bomb developed by DRDO lab ARDE, has a standoff precision strike capability and a range exceeding 80km. It is currently undergoing trial and will be mass produced by private players.

-Smart Anti-airfield weapon (SAAW) is an air-launched smart glide bomb developed by DRDO lab RCI. It has an engagement range of up to 100 km and capable of destroying enemy airfield assets like radars, bunkers, taxi tracks, runways and fuel depots with pin-point accuracy The weapon system is under induction by Armed Forces and is being mass produced by BDL.

-ULPGM is a UAV launched air-to-ground missile, capable of destroying static and moving targets.it is equipped with an imaging infrared seeker for guidance. This system has currently received an LSP order which will be executed by BDL and Adani Defence.

 

Many such projects are under active development, with little information available to the public.

 

 

Future prospects

 

Evolving battlefields and technological breakthroughs have made PGMs evolve from guided munitions to key elements in network centric warfare. The integration of datalink onboard has changed the use case scenario, which raised the system's niche capability to operate in a physical environment while being operated virtually and to change the target mid-course.


Future PGMs will be deployed from unmanned platforms which are coordinated by various manned and unmanned systems in the surrounding, which will drastically reduce the target identification, tracking and engagement time. This includes a network enabled precision guided munition that interfaces with battlefield systems. Effective information exchange among delivery and ISR platforms, satellite assets and C2 structures will be vital for accurate and precise mission execution. Meanwhile, growth in electronic warfare systems has made avionics onboard PGMs capable of withstanding electronic attacks.

 

Conclusion

 

In conclusion, precision guided munitions are significantly influencing the future of military operations in recent global conflicts. However, given India's unique geographical challenges, these munitions may not be a universally effective solution in all scenarios. Growth in AI and machine learning might help train the onboard computer to understand and work precisely in these complex terrains. A substantial advancement in this area would enhance Indian military’s relevance on the global stage while maintaining strategic balance in the area!
