Cyber Threat from Imported Defence Systems

Super-Hercules-Aircraft

India faces a major cyber security challenge from imported Defence products which can come laden with snooping virus or malwares and should thus get involved with the production of weapon systems from their nascent stage, chief of Defence Research and Development Organisation Avinash Chander said on Friday.

Addressing the media at Defexpo 2014, Mr. Chander, who is also the Scientific Adviser to the Defence Minister, said cyber security can be enhanced by getting involved with the software of the projects from the time they are developed so that “cocoons” could be built around them.

Responding to a question on India’s ability to check for malware or snooping devices in advanced systems like the C-17 and C-130J Super Hercules aircraft procured from the United States, Mr. Chander said “when an equipment is bought from outside, you have no control.”

He called for having guidelines to protect systems against subversion. “Cyber security is our biggest security challenge and requires a new paradigm in purchase processes. When we buy, we must buy with security in mind,” he said.

The Scientific Adviser to the Defence Minister said DRDO has also undertaken in a big way the development of cyber technology tools. It has also taken to installation of controlled networks and securing the local networks. Besides, it was working on its own security mobile systems, development of Avdhani processors, and developing its own routers, operating systems and analysis systems.”

INS Arihant: Sea Trial Soon

India’s nuclear submarine INS Arihant is all set to be launched for sea trials in few weeks, giving Navy the capability to respond to nuclear strikes from sea and thereby completing its ‘nuclear triad’. INS Arihant is currently going through harbour acceptance trials.

Attaining nuclear capability by the Navy is crucial for India as the country follows a ‘no first-strike’ policy of nuclear weapons and requires a strong retaliatory capability as a deterrence. INS Arihant which is fitted with 750 kilometres range K-15 nuclear missiles is expected to boost India’s security in the Indian Ocean.

Other submarines, being operated by Indian Navy need frequent trips to the surface for charging of the batteries. INS Arihant has stronger underwater endurance power and better speed than its counterparts. It has been fitted with a indigenous nuclear reactor, which powers the submarine using 80 MW pressurised light-water reactor with enriched uranium fuel.

The INS Arihant has been designed and constructed as a part of the Indian Navy’s Advanced Technology Vessel (ATV) project at the naval dockyard in Visakhapatnam by collaborative efforts of the Indian Navy, BARC and DRDO. Though 60% of the submarine’s body is indigenous, Russians too have assisted in designing it.

Agni-IV: Successful Test Flight

Defence Research and Development Organisation (DRDO) today successfully test fired its 4000 km range, nuclear capable, surface to surface ballistic missile Agni-IV, making it ready for induction into the Army. This was the third success in a row. The missile has already been flight-tested three times. While the maiden launch was a failure, the next two were successful.

The Agni-IV is a strategic missile which can carry a nuclear warhead weighing one tonne. The missile was fired from a road-mobile launcher. This meant it can be moved anywhere in the country and this is its main strength. India’s nuclear deterrence programme received a boost by this test fire.

Agni-IV is a two-stage, solid fueled missile. It weighs 17 tonnes and is 20 metres long. The sophisticated missile is lighter in weight and can withstand temperature of more than 3000 degree Celsius during re-entry.

Army has already deployed Agni-I, II and III missiles, all of which are strategic missiles carrying nuclear warheads, Agni-IV and Agni-V have not been inducted into the Army yet.

Nirbheek: First Women Gun

Giving more power to women to defend themselves and as a tribute to December 2012 ganrape victim Nirbhaya, the Indian Ordnance Factory, Kanpur, has manufactured Nirbheek, a .32 bore light weight revolver, India’s first firearm designed for women. At 500 grams, it is also the first IOF handgun made of titanium alloy.

Priced at Rs 1,22,360, Nirbheek was launched on January 6 and has already received around 80 formal enquiries and over 20 bookings. At least 80% bookings are from women licensees. Described by arms experts as an Indian hybrid of a Webley & Scott and Smith & Wesson, for its simple mechanism and light frame, it is the smallest revolver made in India — an ideal to fit a purse or a small hand bag.

The revolver is capable of firing six rounds loaded in a revolving chamber, hence any misfire of a round does not affect next shot, unlike in a pistol. Keeping in mind the target clientele, the IOF Kanpur has also ordered specially designed boxes lined with velvet to make it more attractive.

Prithvi-II User Trial Successful

Prithvi-ii

Strategic Forces Command (SFC) on Tuesday, 7 Jan 2014 successfully conducted a user trial of surface-to-surface nuclear capable ballistic missile Prithvi-II from the integrated test range at Chandipur as a part of “a scenario-based live launch training exercise”. It has achieved single digit accuracy reaching close to zero circular error probability (CEP).

Such training launches clearly indicate India’s operational readiness to meet any eventuality and also establishes the reliability of this deterrent component of India’s Strategic arsenal.

Prithvi-II class is a single-stage liquid fuelled missile, which is capable of carrying warheads between 500 kg and 1,000 kg and has a strike range of 350 km. Inducted into the SFC in 2003, Prithvi-II was the first missile to be developed by DRDO under the Integrated Guided Missile Development Programme (IGMDP).

Prithvi was initially supposed to be a 150 km “tactical” battlefield missile with conventional warheads but later its role was expanded to include the “strategic” one as well with 500 to 1000 kg nuclear payloads. Prithvi-II was developed to succeed Prithvi-I, a tactical missile which has been phased out.

The naval version of the Prithvi-II is Dhanush, which can carry a nuclear warhead of 500 kg over 250 km.
