Turkey has unveiled a new heavy precision weapon that immediately draws attention: the NEB Hayalet. According to the Turkish authorities, the bomb first penetrated seven metres of reinforced concrete during tests, followed by one and a half metres of sand, before driving tens of metres further into the ground.
The footage leaves little to the imagination. A long, dark bomb on a test rig, bearing the markings of the Turkish Ministry of Defence and the defence industry’s research department. Shortly afterwards comes the impact.
Deep penetration
The NEB Hayalet is a so-called penetration bomb. This type of weapon is designed not to explode immediately on impact, but first to drive deep into concrete or earth. Only then does the explosion follow.
In the recent test, the bomb was dropped from an F-16. According to Turkish sources, the weapon penetrated to a depth of about 90 metres in the ground after first breaking through a heavy concrete structure. That is considerable. By comparison, many standard bunker busters are designed for a few metres of concrete, depending on angle and speed.
Penetration depends on three factors: mass, speed and construction. The heavier and faster the bomb, the greater its penetrating power. The nose of these weapons is made of extremely hard steel to limit deformation on impact.
Dropped from an F-16
That the bomb was tested from an F-16 is strategically relevant. The F-16 is still the backbone of the Turkish air force. Integration on this platform means the weapon can be used immediately without a new aircraft type.
The Turkish defence industry has been working for years to increase its self-reliance. The country previously developed its own guided bombs and cruise missiles. With the NEB Hayalet, it now also covers the heavy penetration segment.
A bunker buster is usually used against hardened targets such as command centres, underground storage facilities or deeply buried infrastructure. Exactly those kinds of targets have become popular in recent years in conflict zones where opponents dig in to avoid air strikes.
Technical design
Few exact specifications have been released. It is visible, however, that it is a long, cylindrical bomb with a streamlined nose and stabilising fins at the rear. Its size suggests a weapon in the 900 to 1,000 kilogram class.
A penetration bomb works differently from conventional explosive bombs. Where a standard bomb mainly causes surface damage through blast and fragmentation, a bunker buster is designed to use kinetic energy — the energy released by mass and speed on impact.
Penetration is usually followed by delayed detonation. That fraction of a second of delay ensures the explosion takes place inside the target, not outside it.
Comparison with other systems
Other countries have long had similar weapons. The United States, for example, uses heavy bunker busters for attacks on underground installations. Russia and Israel also have penetration weapons in their arsenals.
What sets the Turkish test apart is the combination of deep ground penetration after breaking through concrete. Driving seventy to ninety metres into the earth means that deeply buried structures also become vulnerable.
That could be relevant in scenarios in which opponents use tunnel systems or underground storage. Recent conflicts have shown that air strikes often have limited effect on well-protected underground targets.
Domestic production
The NEB Hayalet was developed within the Turkish defence industry under the supervision of the Ministry of Defence. Turkey has been investing heavily in domestic production capacity for years. The aim is to be less dependent on foreign suppliers, especially in times of political tension.
With its own penetration weapons, Ankara can equip its air force independently, without export restrictions or political conditions from other countries.
The weapon fits into a broader modernisation drive. Besides guided bombs, Turkey is also developing long-range missiles, drones and air defence systems.
Operational use
Integration on the F-16 suggests the weapon could become operational relatively quickly. The platform can carry heavy loads and has modern targeting systems for precision strikes.
Whether the NEB Hayalet also includes satellite guidance or laser-guided components has not been confirmed. Modern bunker busters often combine GPS navigation with internal inertial navigation. That system works with gyroscopes and accelerometers and keeps working when GPS is jammed.
In any case, the footage shows a weapon intended for strategic targets. Not light ammunition for the battlefield, but an instrument for taking out heavily protected objects.
The name “Hayalet” means “ghost”. A fitting name for a weapon that only unleashes its destructive power deep underground.
