ember 15, 2008: A joint air exercise between the air forces of India and Singapore is in progress at the Kalaikunda air base in West Bengal and will conclude on December 15, IAF sources said today.
The bilateral air exercise codenamed SINDEX began on November 24.
The Royal Singapore Air Force (RSAF) has brought its F-16C/D fighter aircraft and IAF its MiG-27 ground attack fighters in the 20-day war games."SINDEX provides a valuable opportunity to both the air forces to interact in realistic and challenging conditions and learn from each other's experiences," IAF sources said, when asked about the objectives set for the exercise.
"This is the sixth exercise of the SINDEX series to be conducted in India and second after the two sides signed a bilateral agreement for conducting joint military training and exercises in India," sources said.
The exercises have helped the IAF and RSAF, sources said, to understand each other well and operate jointly.The two sides have warm defence relations, which include regular exchange visits and professional interaction, they added
Thales UK's naval business has now been awarded the prime contractorship to upgrade the vessels with a technologically advanced minehunting system which will include fitting the new hull-mounted Sonar 2193 system, propulsion, command and control systems, and mine disposal systems.
The ships are expected to enter service with the Lithuanian Navy by 2011.
The proliferation of so-called double-digit surface-to-air missile systems - such as the Almaz Antey SA-20 (S-300PMU1/S-300PMU2) - poses an increasing threat to nonstealthy aircraft, and will force changes in tactics and operational planning. The SA-20 has an engagement envelope of roughly 100 mi., and Iran may be signed up for the S-300PMU-2 variant with even greater range.
Russia could use Belarus as the route for a sale, allowing Moscow to deny any direct involvement, says a U.S. official. It would likely take the Iranian armed forces as long as 24 months to become proficient in the operation of the SA-20; however, any deal would almost certainly cover training support in the interim. Israel might be tempted to preemptively strike suspected nuclear sites prior to the SA-20 becoming operational, or even try to hamper delivery. "The beginning of proliferation of double-digit SAMs is more of a concern than the potential air threats [such as Russia's Sukhoi Su-35 and China's Chengdu J-10] that are coming into service," says the government official.
The presence of Russian double-digit long-range SAM systems in the region during the recent Georgian incursion had a direct impact on NATO planning - resulting in a decision not to use the Boeing E-3 AWACS for surveillance.
The SA-20 and, even more so, the SA-21 Growler (S-400) now entering service pose an increasing problem for mission planners using conventional strike aircraft. While low-observable aircraft offer greater latitude for operations, they are not totally immune to air defenses.
The Lockheed Martin F-22 with its all-aspect, -40-dBsm. radar cross-section signature can operate within the engagement envelope of the SA-20 and SA-21. But the Lockheed Martin F-35 with its -30-dBsm. signature, but not all-aspect stealth, is at greater risk. The rear quadrant of the F-35, particularly around the engine-exhaust area, is not as stealthy as the F-22.
Because of its aging stealth design, the Northrop Grumman B-2 also has limitations in the amount of time it can spend within the range of double-digit SAM systems, since small signature clues can become cumulative and offer a firing solution. The U.S.'s next-generation bomber program is aimed at developing a low-observable platform capable of operating irrespective of the threat from systems of the SA-21 class.
During the recent conflict between Georgia and Russia, the caution with which double-digit SAMs are treated was obvious. NATO wanted to monitor the fighting and refugee problems and track combat forces with its fleet of recently updated E-3 AWACS surveillance aircraft. They were banned from the area because the Russian attack columns included mobile SA-20 batteries. From their location in the Georgian breakaway region of Abkhazia, these SAMs covered airspace over the eastern Black Sea where the E-3s would have needed to operate.
"If a coalition organization wanted to establish [surveillance or reconnaissance] flights or a no-flight zone in an area populated by double-digit SAMS, you couldn't do it with nonstealthy aircraft," the government official says. "These modern weapon systems are going to deny us strategic and operational options that in the past we haven't had to worry about."
The Iranian deployment of the SA-20 would most directly be a threat to Israel's fleet of advanced, but nonstealthy, F-15Is and F-16Is. Israel would need to rely on countermeasures - such as airborne jamming, false-target creation and network attack - rather than on platform survivability to counter the introduction of the Gargoyle.
More capable point-defense systems - which would likely be used to protect SA-20 sites, for example - are also being introduced into the region. Syria is acquiring the SA-22 Greyhound (KBP Pantsyr), which uses a vehicle-mounted combination of cannon and missiles intended to provide defense against aircraft, helicopters, precision-guided munitions and cruise missiles.
New threats, involving advances in commercially available electronics, continue to rapidly mutate in the area of secure communications and command and control, as demonstrated in Mumbai, India. During the recent attack, gunmen talked by cell phone and Voice Over Internet Protocol (VOIP) to their commanders in Pakistan for orders about avoiding police, attacking additional sites, and selecting hostages for execution.
And during the 2006 fighting between Israel and Hezbollah in Lebanon, the non-state group was able to set up command-and-control networks - using commercially available, Chinese-built, high-power cordless phones - to shift combatants and rocket launchers. These messages could not be intercepted by the Lebanese or Israeli governments.
"[Part of the threat is] the new phones that are coming out with GSM, Satphone, Bluetooth, 80211G and 80216 [technologies] all built into one handset," says an electronic warfare specialist in the U.S. aerospace industry. "It's already happened. A multifunction handset switches you through all the options to find a usable route. If your GSM link goes out, it will automatically hook up to the nearest 80211G link, get the message to an Internet node and then go VOIP. That kind of connection technology is here, and it's cheap for the bad guys. All you have to do is be clever about how you use it for command and control."
Recent pictures of the interior of a new Chinese surface-to-air-missile command-and-control vehicle show two Lenovo laptops and the commander of the integrated air defense system talking on a Blackberry. In the battery's briefing vehicle, there's a VOIP connection. These are all good, cheap commercial products.
Defense officials say that with the new telecommunications used by opponents, U.S. planners have to be much more detailed about how electronic attack is conducted against certain networked, computer-controlled threats such as integrated air defenses.
The question arises: Is there any good news in this scenario? Perhaps there is at the intersection of electronic attack and cyberwarfare (a new specialty called special-purpose electronic attack, or SPEA) and at the overlap of electronic attack and high-power microwave weapons (called nontraditional electronic attack, or NTEA).
SPEA moves into cyberwarfare because operators are looking at more than jamming external emissions. They are dealing with affecting layers of digital instructions, called protocols, that run the network. They are using electronic attack, but it is against a computer network and not just a radar or radio signal. So there are new procedures that can be used in the electronic attack domain that are special and unique. NTEA involves producing long-lasting, instead of temporary, effects on enemy electronics.
"It's not solely about effective radiated power [for jamming] anymore, it's about control," the EW specialists says. "It's about what part of the protocol stack can you get to and, possibly, take control of. A lot of it is not about preventing them from communicating; we're just controlling it in some way."
