Hatf I (Urdu: حتف‎) is a subsonic battlefield range ballistic missile (BRBM) which entered service with the Pakistan Army in the early 1990s. It is deployed as an artillery rocket and has been replaced by the improved Hatf-IA and Hatf-IB, which have a maximum range of 100 km.

Hatf is an Arabic word meaning "Deadly" or "Vengeance". The name comes from the sword of Muhammed, Al-Hataf [1]

Development and design[edit]

Hatf I was designed in the 1980s as a highly mobile missile for tactical use. The design is said to have been derived from the second-stage of the French Eridan missile system.[2] Its major use is as an unguided general bombardment weapon, to be fired across a battlefield or at a general target area.[2] If properly aimed, it can hit within several hundred meters of the target area. The missile is low cost and easy to produce and maintain in large numbers. The Hatf I missile development program dates back to the 1980s. The Hatf-I was officially revealed by Pakistani officials in 1989 and it is believed to have entered service in 1992.[3]

The Hatf I has a range of approximately 70 km (43 mi) and can carry a 500 kg conventional or non-conventional warhead. As it is unguided, it should be considered a long-range artillery shell, with the location of the impact depending upon the proper direction, angle of launch and the ability of the missile to fly straight. The Hatf-I is deployed with high explosive or cluster munitions, although it can theoretically carry a tactical nuclear weapon. The missile has a diameter of 0.56 m and is 6 m in length. It uses a single-stage solid propellant rocket motor.[2]

The Hatf IA and Hatf IB are upgraded versions with improved range and accuracy. The Hatf IA increased maximum range to 100 km by using an improved rocket motor and lighter materials in the missile's construction. The dimensions and the payload capacity remain the same. Hatf-IA is believed to have entered service in 1995.[2]

The Hatf IB represents the final evolution of the Hatf I missile system. It includes an inertial guidance system that considerably improves the accuracy of the missile and is otherwise identical to the Hatf IA, retaining the maximum range of 100 km and payload of 500 kg. The inertial guidance system allows the missile to be used as an artillery rocket against enemy military encampments or storage depots etc. The missile system is designed to be used like an artillery system, with 5-6 missiles fired simultaneously at the target area. Being a ballistic missile the Hatf-IB would reach its target much quicker than an ordinary artillery shell giving the target little warning to take evasive action.

Hatf-IB was first flight tested in February 2000. All current Hatf-I missiles have been upgraded to Hatf-IB standard as of 2001. The system is operational with Pakistan's armed forces.[2][4]
