Merkava Tank Specs, Armor, Trophy Protection and the New Barak Variant

The Merkava is Israel’s main battle tank and one of the most unusual designs in the world. Built around the idea that crew survival comes first, it puts the engine at the front, a door at the back and, since 2011, an active protection system that shoots down incoming missiles. In 2026 the latest Merkava Mk 4 Barak brings artificial intelligence and helmet-mounted displays into the turret.
- Country: Israel; in service since 1979 (Mk 4 since 2004)
- Weight: ~65 tonnes; crew: 4
- Main gun: 120 mm, can fire LAHAT missiles
- Protection: Trophy active protection system
- Latest variant: Mk 4 Barak (AI, IronVision)
A tank built around its crew
The Merkava program began in the 1970s, after heavy tank losses in the 1973 Yom Kippur War convinced Israel it needed a tank designed for its own needs rather than imports. Its designers placed the engine in the front of the hull to act as extra armor and gave the tank a rear hatch, so the crew can enter and exit under cover and the tank can carry a few soldiers or a stretcher.
Merkava Mk 4 specs
The Mk 4, in service since 2004, weighs around 65 tonnes and carries a crew of four. It is armed with a 120 mm smoothbore gun that can fire guided LAHAT anti-tank missiles as well as conventional rounds, plus machine guns and a 60 mm mortar. A 1,500 hp diesel engine gives a top speed of about 64 km/h. Its modular armor can be replaced quickly when damaged or upgraded.
Trophy: the game-changer
The Merkava Mk 4 was the first tank to use an active protection system in combat. Rafael’s Trophy uses radar to detect incoming rockets and anti-tank missiles, then fires a cloud of projectiles to destroy them before impact. It entered operational use in 2011 and has since been bought by the US Army for the Abrams and by Germany for the Leopard 2.
Mk 4 Barak: the “smart” Merkava
Unveiled in 2023, the Barak variant adds AI-assisted target detection, a 360-degree sensor suite and the IronVision helmet, which lets the commander “see through” the armor using external cameras. It is designed for urban fighting, where threats can come from every direction at close range.
Combat record
Merkavas fought in Lebanon in 1982 and 2006, and played a central role in the Gaza war that began in October 2023 and in later operations in southern Lebanon. They suffered losses to roadside bombs and anti-tank weapons, but Trophy and crew-protection features are credited with saving many lives.
Why it matters
The Merkava has rarely been exported, and Israel has historically kept it for its own army. Its ideas, however, have spread worldwide: active protection, modular armor and crew-first design are now standard requirements for the next generation of Western tanks.
