India has achieved a significant milestone in defence technology with the development and certification of SEBEX 2, a new explosive that is 2.01 times more lethal than standard TNT (Trinitrotoluene). This high-performance explosive, evaluated and certified by the Indian Navy, represents one of the most powerful non-nuclear explosives globally. The advancement is expected to substantially enhance the destructive power of various munitions, including warheads, aerial bombs, and artillery shells, without increasing their weight.
Revolutionary Advancements in Lethality
The lethality of an explosive is often measured in terms of TNT equivalence, which indicates the explosive’s destructive power compared to TNT. Currently, the most potent conventional explosive used in India, such as in the BrahMos missile warhead, has a TNT equivalence of about 1.50. In contrast, most conventional explosives globally have a TNT equivalence of 1.25 to 1.30. SEBEX 2, with its TNT equivalence of 2.01, marks a significant leap in destructive capability.
Developed by Economic Explosives Limited (EEL) under the Make in India initiative, SEBEX 2 is based on high-melting explosive (HMX) technology. This composition significantly enhances the lethality of munitions that rely on blast and fragmentation effects to damage targets. The new formulation has undergone extensive testing and evaluation by the Navy, culminating in its certification under the Defence Export Promotion Scheme.
Potential for Global Impact
The development of SEBEX 2 not only boosts India’s defence capabilities but also positions the country as a significant player in the global defence market. The explosive’s high lethality and improved efficiency make it an attractive option for forces worldwide looking to upgrade their existing weapon systems. The potential for export is substantial, as militaries around the globe seek to enhance their offensive capabilities without increasing the weight or size of their munitions.
Further Innovations in Explosives
EEL is not stopping with SEBEX 2. The company is also working on another variant that is expected to have an explosive power graded at 2.3 times that of TNT. This new variant is anticipated to be ready within the next six months, promising even greater enhancements in the lethality of munitions.
In addition to SEBEX 2, the Navy has also certified other innovative explosives developed by EEL. SITBEX1, the company’s first thermobaric explosive, generates prolonged blast durations with intense heat, making it highly effective against enemy bunkers, tunnels, and other fortified positions. This explosive has been used in recent conflicts to cause large-scale damage on the battlefield.
Enhanced Safety with SIMEX 4
Safety is a critical concern in the storage, transport, and operation of explosives. To address this, the Navy has certified SIMEX 4, an insensitive munition developed by EEL. SIMEX 4 is much safer than standard explosives, significantly reducing the risk of accidental ignition. This feature makes it particularly suitable for applications where safety is paramount, such as in torpedo warheads housed in the confined spaces of submarines.
Proven Track Record
EEL’s development of these advanced explosives under the Make in India initiative showcases the country’s growing capability in defence technology. The use of high-melting explosive (HMX) in these formulations underscores their enhanced performance and reliability. These innovations not only improve the effectiveness of India’s munitions but also contribute to the broader goal of self-reliance in defence production.
