LLAD guns

Also known as
  • low-level air defence guns
  • low-level air defense guns
  • LLAD gun layer

LLAD guns are India's low-level air-defense gun layer, built around modernized 40 mm L/70 batteries and 23 mm twin-barrel mounts for point defense against low-flying aircraft, drones, and loitering munitions. During the 2025 India-Pakistan Conflict, Indian official reporting placed them inside Operation Sindoor's layered air-defense network alongside MANPADS and longer-range surface-to-air missiles.

Indian Army air-defense units fielded low-level air-defense guns in Operation Sindoor as part of a layered defense against Pakistani drones and loitering munitions, working alongside MANPADS and longer-range surface-to-air missiles.

Documented Service Mix

Indian reporting treats LLAD guns as a mixed low-level layer rather than a single model. Modernized 40 mm L/70 batteries and 23 mm twin-barrel mounts are the representative families most often described in service.

Timeline

LLAD guns Key Events

  1. Representative gun families enter Indian service

    Defense reporting describes the 40 mm L/70 and 23 mm twin-barrel low-level air-defense families as long-serving Indian Army point-defense guns that became the backbone of the LLAD layer.

  2. Modernization shifts the guns toward electric laying and better sights

    Indian LLAD gun upgrades moved away from purely manual operation toward electric laying, improved sighting, electro-optical fire-control, thermal imaging, laser ranging, and radar-interface improvements for closer-in air defense.

  3. Operation Sindoor puts LLAD guns in the layered air-defense fight

    PIB said Indian Army air-defense units used LLAD guns with MANPADS and longer-range surface-to-air missiles to counter Pakistani drone and loitering-munition attacks during Operation Sindoor.

Its towed and naval variants remained in service through upgrades, with source-backed modern use including Lithuanian-supplied guns in Ukrainian air defense and Indian upgraded L/70 guns used as a short-range counter-drone layer during the 2025 India-Pakistan Conflict.

The family includes the original IFG and lighter LFG, with Field Gun Factory Kanpur and Gun Carriage Factory Jabalpur tied to production and support, and 2020s reporting still connecting the guns to border deployments, ceremonial salutes, and automatic-laying modernization.

It fills the layer between short-range point defenses and long-range strategic SAMs, with six-canister land launchers, radar and command vehicles, and a naval VLS fit on Type 054A-family frigates. In the 2025 India-Pakistan Conflict, Indian government and Indian press reporting identified Pakistan as relying on imported HQ-16 systems during Operation Sindoor, making it a documented part of Pakistan's contested air-defense picture.

The record is most directly documented in the 1988 Tanker War phase of the 1980 Iran-Iraq War, where a Sassan platform 23 mm gun mount engaged U.S. forces, and in the 2020 United States-Iran Conflict, where ZU-23-2-type guns appeared as low-altitude point-defense threats and strike targets.
