The Navy’s Amazing Ocean-Powered Underwater Drone
While you were out shopping Sunday for those last-minute holiday gifts, the Navy pushed ahead with its own vision of an underwater sugar plum: a fleet of “long endurance, transoceanic gliders harvesting all energy from the ocean thermocline.”
And you thought Jules Verne died in 1905.
Fact is, the Navy has been seeking—pretty much under the surface—a way to do underwater what the Air Force has been doing in the sky: prowl stealthily for long periods of time, and gather the kind of data that could turn the tide in war.
The Navy’s goal is to send an underwater drone, which it calls a “glider,” on a roller-coaster-like path for up to five years. A fleet of them could swarm an enemy coastline, helping the Navy hunt down minefields and target enemy submarines.
Unlike their airborne cousins, Navy gliders are not powered by aviation fuel. Instead, they draw energy from the ocean’s thermocline, a pair of layers of warm water near the surface and chillier water below.
The glider changes its density, relative to the outside water, causing the 5-foot (1.5m)-long torpedo-like vehicle to either rise or sink—a process called hydraulic buoyancy. Its stubby wings translate some of that up-and-down motion into a forward speed of about a mile (1.6 km) an hour in a sawtooth pattern. As it regularly approaches the surface, an air bladder in the tail inflates to stick an antenna out of the water so it can transmit what it has learned to whatever Captain Nemo dispatched it to the depths.
Much of the work such gliders do is oceanographic in nature, collecting data about the water’s temperature, salinity, clarity, currents and eddies. Such information is critical for calibrating sonar to ensure it provides the most accurate underwater picture possible. But there are additional efforts underway to convert such data into militarily-handy information.
Slocum Gliders rise and fall as they traverse the ocean’s depths, transmitting what they learn via tail-mounted antennas that periodically break through the water’s surface.
The Navy’s Sunday contract announcement added a scant $203,731 to a contract it has with Teledyne Benthos, Inc., for continued “research efforts” into its Slocum Gliders (named for Captain Joshua Slocum, who sailed alone around the world in a 37-foot sloop between 1895 and 1898). “Carrying a wide variety of sensors, they can be programmed to patrol for weeks at a time, surfacing to transmit their data to shore while downloading new instructions at regular intervals, realizing a substantial cost savings compared to traditional surface ships,” the company’s Webb Research division says. The Webb unit is located in East Falmouth, Mass., and its Slocum Glider is the brainchild of Douglas Webb, a former researcher at the nearby Woods Hole Oceanographic Institution.
In 2009, the Navy issued a $56.2 million contract for up to 150 of the “Littoral Battlespace-Sensing” gliders to be delivered by 2014. The Navy has said it is investing in the field because such information could prove vital “for mine countermeasures and other tasks important to expeditionary warfare. . .ultimately reducing or eliminating the need for sailors and Marines to enter the dangerous shallow waters just off shore in order to clear mines in preparation for expeditionary operations.”
A NATO report last year examined the feasibility of launching Slocum Gliders from torpedo tubes instead of T-AGS oceanographic surveillance ships. “Operating gliders from submarines represents a step forward to embedding this technology into naval operations,” it said. “Unlike surface ships, submarines are stealth platforms that could transit denied areas while releasing a glider fleet.”
Navy Captain Walt Luthiger, a submariner, said an exercise using such gliders proved their mettle in yet another arena. “The environmental information provided by the gliders has proved valuable,” he told NATO public affairs in 2011, “and helped everyone in that very difficult job of finding submarines that don’t want to be found.”

Chinese aircraft carrier Liaoning's combat capability tested: Photo
"The Liaoning successfully performed several tests of the combat system today and organized for the first time comprehensive combat training," the People's Liberation Army navy said in a statement. "Through this operation, we tested the carrier's combat capability and tried the performance of its propulsion and seaworthiness."
This is the first time the Liaoning has made a long-distance training voyage since it was commissioned into the PLA navy last year, the statement said, adding that the mission is characterized by a large number of tests, rigorous standards, complicated circumstances as well as collaboration with multiple military units.
The ship left its homeport of Qingdao, Shandong province, on Nov 26 and anchored at a naval base in Sanya, Hainan province, three days later. On Dec 5, it set out on the training mission.
Two missile destroyers, the Shenyang and Shijiazhuang, and two missile frigates, the Yantai and Weifang, participated in the mission. They escorted the carrier along the whole voyage from Qingdao to Sanya.
"The South China Sea has deep waters, strong wind and big waves, making it a suitable place for the aircraft carrier to conduct tests and training," said Senior Captain Zhang Zheng, captain of the Liaoning.
Crewmembers also have performed a series of tests on items such as the ship structure's resistance to stress, sailing speed in deep waters and stability of weapons and equipment, he added, noting that combat departments practiced exercises to defend incoming hostile aircraft, ships and submarines.
Several types of aircraft, combat ships and submarines were dispatched to cooperate with the carrier during the mission, which simulates real combat situations, according to Zhang.
After entering active service in September 2012, the Liaoning has carried out 12 sea trials and tests, including landings and takeoffs for the J-15 fighter jet.
The ship is still in the test and exercise stage, according to Senior Captain Mei Wen, Liaoning's political commissar.
"We have commanded the basic capability to operate and coordinate fighter jets and helicopters with the carrier," Mei said. "We have accumulated much experience in logistic support for the J-15 fighters and improved a lot in terms of damage control and handling of equipment malfunctions."

China plans to build a 110,000 ton 'super aircraft carrier' to rival US naval power
Chinese website qianzhan.com cites "top People's Liberation Army" sources as saying the 110,000-ton aircraft carrier should be launched by 2020.
"By that time, China will be able to confront the most advanced US carrier-based fighter jets in high sea," the Chinese-language article reads.
The news follows rising tensions in the South and East China Seas where the most recent incident involved a near-collision with a US cruiser shadowing China's first aircraft carrier, the refurbished Liaoning which was purchased from Ukraine.

China's first homegrown aircraft carrier will be a larger version of Liaoning. The first of two such vessels is due to hit the water in 2015.
The design is reportedly based on drawings from the former Soviet Union of a nuclear-powered, 80,000 ton vessel capable of carrying 60 aircraft.
"Despite their lack of experience, Chinese scientific research personnel have the ambition to overcome various difficulties to master lots of new technologies and techniques in building China's own powerful aircraft carrier," the article reads.

Iranian Fighter Jets Hit Air, Ground Targets in Massive Wargames

Iranian fighter jets drop bombs during the Fada’eeyan-e Harim-e Velayat 4 (Defenders of Velayat Sanctuary 4) drill which ended on December 21, 2013.
TEHRAN (Tasnim) – Fighter jets of the Islamic Republic of Iran Air Force (IRIAF) could successfully annihilate both fixed and mobile targets in the air and on the ground during the main phase of combat exercises in the country’s southern regions on Saturday.
The strategic Sukhoi Su-24 fighter-bombers along with F-4 Phantom combat planes of the IRIAF accomplished all the tasks they were set to do during the second day of the main phase of large-scale wargames, codenamed Fadaeeyan-e Harim-e Velayat 4 (Devotees of Velayat Airspace 4), on Saturday morning, spokesman for the air maneuvers, General Hossein Chitforoush, said on December 21.
The IRIAF launched the main phase of the massive aerial drills, which involves combat exercises, in the country’s southern regions on Friday.
Lieutenant Commander of the Iranian Air Force Brigadier General Alireza Barkhor had announced earlier that the ongoing wargames over the Persian Gulf were the fourth such military drills conducted by the IRIAF.
Units from all IRIAF bases are taking part in the three-phase drills. The maneuvers are part of annual exercises aimed at testing indigenous air defense systems, improving the units’ combat readiness and displaying the country’s military might and achievements, Barkhor said.
As regards the main phase of the wargames, General Chitforoush said on Saturday that the F-5 fighter aircraft, the Mirage and the Saeqeh (Thunderbolt) fighters managed to carry out operations including aerial interception and air-to-ground shooting at predefined targets until midnight Saturday.
“As of this morning, the Saeqeh (Thunderbolt) and the Mirage aircraft hit their aerial targets in long-range distances,” the General said today.
He also noted that the Sukhoi Su-24 fighter-bombers, carrying home-made optimized missiles with pinpoint accuracy, could destroy ground targets and those floating in the sea.
And a few hours ago, the general added, the F-4 interceptor fighter jets fired the upgraded Maverick missiles, as well as smart rockets with pinpoint accuracy, at the naval targets successfully.
Chitforoush has stated earlier that the latest drills feature long-range flights by fighter jets without aerial refueling as well as pinpoint targeting using bombs and rockets in air-to-surface and air-to-air operations.
“Air-to-air shooting operations, shooting at aerial targets of different speeds at diverse altitudes, air-to-ground shooting and bombardment with various kinds of home-made rockets and bombs are among the other major parts of these drills that would be conducted in a large area,” the spokesman said on Friday.
The third edition of these drills was held in Iran's northwestern regions in September 2012.
Meanwhile, Brigadier General Alireza Barkhor has said that the country’s Air Force is ready to hold joint air drills with Middle Eastern countries, adding that the ongoing exercises carry a message of peace, friendship and security for all regional countries.
“The Islamic Republic of Iran Air Force, within the framework of the (Islamic) establishment’s policies, is prepared to stage joint maneuvers with regional states,” Barkhor said in the southern port city of Bandar Abbas on Friday.
Iranian pilots and air force staffs hold the Fada’eeyan-e Harim-e Velayat 4 (Defenders of Velayat Sanctuary 4) military maneuvers in the southern port city of Bandar Abbas on December 21 and 22, 2013.
A-10: Close Air Support Wonder Weapon Or Boneyard Bound?
WASHINGTON: The A-10 Warthog is ugly, tough, lethal, and fairly flexible. Its famous 30mm gun can destroy tanks or other armored vehicles with remarkable efficiency, not to mention enemy troops. Its titanium tub of a cockpit protects the plane’s pilot from most ground fire. Its pilots are trained to fly low and slow and to kill the enemy even when he is within yards of US forces. The Army and Marines love the Warthog.
In short, the A-10 appears to be the exemplar of Close Air Support, protecting Marines and Army troops when they face being overwhelmed by the enemy. Some members of Congress, with an eye on bases in their states and districts, love the plane as well and have championed legislation blocking the plane’s retirement.
Why, then, people ask, is the Air Force seriously considering sending the Warthogs to the great boneyard and their pilots to other missions? The answer is complex, but it boils down to three things: money, smart bombs, and threats.
First and foremost, retiring the entire A-10 fleet would save the Air Force $3.7 billion from 2015 to 2019. Retiring just some or even most of the A-10s wouldn’t reap nearly the same savings, because there are fixed costs in training and maintenance you can’t get rid off as long as you keep any planes.
Second, thanks to the wonder of smart bombs, most of the A-10′s mission can be done by other, less specialized aircraft. That wasn’t technologically possible when the A-10 first entered service in 1975. But in Afghanistan and Iraq, precision-guided munitions from faster-flying fighters and even heavy bombers have actually provided the overwhelming majority — 80 percent — of close air support.
Third, we’re not the only people with smart weapons. The Taliban and the Iraqi insurgents had at most a handful of shoulder-fired anti-aircraft missiles — known in the trade as Man-portable Air Defense Systems, or MANPADS — but an unknown number of MANPADS were smuggled out of Libya after Qaddafi fell, and the missiles on the black market are getting more sophisticated all the time.
That’s why the Air Force has planned for at least the last 15 years to replace the A-10s with the F-35A, its version of the JSF, which will reach initial operational capability (IOC) by the end of 2016. The F-35A will not only carry smart bombs but also have new, sophisticated sensors to guide them to ground targets — and it will fly much faster and higher than the A-10 can, making it a much harder target. While the JSF can’t carry the Warthog’s massive 30 mm gun, it does have a highly accurate 25 mm gun and 182 rounds of ammunition. (I asked Gen. Robin Rand, head of the Air Force’s Air Education and Training Command, last Friday if the F-35 carried enough ammunition to do the CAS mission. He said yes.)
The B and C F-35 models can be fitted with a gun pod that carries 220 rounds but the pod disrupts the plane’s stealthy profile.
The Air Force has a long history of appearing to want to abandon the Close Air Support mission and stick with fighters and bombers, though there is no sign of that from the current Air Force leaders or their immediate predecessors. This unfortunate history means many observers still distrust the Air Force rationales for shutting down the A-10 fleet.
Air Force Chief of Staff Gen. Mark Welsh and his colleagues argue that in these days of declining budgets and the demands of enormous theaters such as the Pacific they must buy multi-role aircraft like the F-35 and the new Long Range Strike system. Single-mission aircraft, no matter how well suited they are to that mission, are just too expensive and limited.
Those don’t seem unreasonable arguments, on their face. But the Air Force’s history of institutional indifference to the CAS mission combines with the broadly-held belief that no aircraft can do the CAS mission as well as the A-10 to spark opposition from ground pounders and Congress in particular.
We spoke with the Army, the service with the most to lose should close air support diminish in effectiveness, and Air Force pilots who fly CAS missions to get both the official and off-the-record views. The official Army, in the form of Maj. Gen. Bill Hix, deputy director of the influential Training and Doctrine Command (TRADOC) Army Capabilities Integration Center, was surprisingly understanding of the Air Force’s idea to shutter the fleet. But Hix also offered a nuanced critique of the current CAS capabilities, in particular the A-10′s ability to fly low and slow and deliver firepower in bad weather.
“If the [A-10] aircraft and the specifically trained pilots go away, this mission will become a distant requirement hastily met with pilots who have been brought up on OCA [Offensive Counter-Air] and DCA (Defensive Counter-Air operations], and CAS that is provided will consist primarily of fast air-dropping JDAMs and other smart bombs on targets designated from the ground and then transitioning out of the area due to limited loiter time,” Hix said in an email.
He listed some very specific conditions where the A-10 and its ordnance are awfully useful:
- When ”flying cover over outposts where attack helicopters can’t get (high altitude areas [e.g.] above 10,000 feet in the mountainous areas of Eastern Afghanistan for instance) and other USAF aircraft cannot get down/under the weather or fly in tight spaces (F-16, et al) or are too limited in numbers (AC-130).”
- When “there is little to no air-to-air/IADs [integrated air defense system] threat and its use eases the demand for artillery and ground logistics requirements to support that artillery (cannon or rocket)[:] think of the support provided by Warthog pilots during the march to Baghdad in 2003); and the 30mm [gun], which is unique and intimidating to those on the receiving end, but not as precise as the gun on the AH-64 or the AC-130.”
- He also made the crucial point, unaddressed by most in the Air Force, that the A-10 also serves as flying artillery, which is very useful in some situations. “CAS,” he writes, “is a complement to artillery and other indirect and air to surface fire support.”
Bottom line for the Army, per Hix: “That complementary mix of precision, area fires, sustained coverage, persistence, responsiveness and moral and physical effect remain important to success in ground combat; the A-10 carries a heavy complement of ordnance, while many other alternatives, like armed UAS, are more limited in their payloads; the A-10 is a good capability to have in the mix and even in limited numbers can continue to provide very useful and hard to replicate support on to ground troops.”
Note that reference to “limited numbers.” That seems to indicate the Army would accept retirement of much of the fleet but really wants the Air Force to keep some A-10s. But the Air Force makes the simple point that its big savings of $3.7 billion come only when it retires the entire fleet and gets rid of fixed overhead costs. As any student of aircraft acquisition knows, buying the planes is pretty cheap. More than three-quarters of a airborne weapon system’s costs typically come from parts, operations and maintenance.
The background view from a senior Army official was surprisingly accepting of the Air Force’s dilemma: “Tough times for all services and we have to leave it up to our counterparts to identify the best way forward to meet the CAS demands from the ground.”
Requests for air support, of course, aren’t the only thing coming from the ground. There’s also anti-aircraft fire — everything from MANPADS to sophisticated air defense missiles.
“I didn’t see the missile coming[;] my flight leader didn’t see the missile coming; my first indication of a missile launch was when it impacted my aircraft,” recalled Lt. Col. Kim Campbell, whose A-10 was hit over Baghdad in 2003. Fragments shredded much of the aircraft and cut its hydraulic control lines. But the plane’s famous titanium bathtub around the pilot kept Campbell alive, and amazingly, she managed to fly the wounded plane back to base.
Campbell argues the latest model, the A-10C, has better sensors and self-defense systems. “The A-10 has improved significantly,” she told Breaking Defense. “We’re better able to operate in these threat environments.”
But while the A-10 has been upgraded to handle some anti-aircraft threats, they still fly low and slow right into the enemy’s defenses. And in the air combat game, speed and advanced electronics are life.
To get a multi-role fighter pilot’s perspective, I spoke with an Air Force F-15E pilot (now a B-2 pilot), Capt. Michal Polidor, who was awarded the Distinguished Flying Cross for a 2009 close air support mission in Afghanistan. The F-15E was not designed for CAS but neither was the B-1 bomber, which along with the F-18 and other multirole aircraft, have provided more than three quarters of close air support since the terror attacks of 2001. Laser-guided and GPS-guided bombs and rockets have made this possible, along with intensive CAS training for multi-role pilots and greatly improved coordination with ground forces through Joint Terminal Attack Controllers (JTACs).
Polidor was called by a JTAC to support 80 troops in danger of being overrun by massed Taliban forces eager to destroy Outpost Keating, a badly positioned base in Afghanistan that the enemy threw an estimated 300 fighters at in hopes of destroying it. He strafed a switchback road and dropped a mix of four bombs. Polidor was part of a fleet of 19 aircraft, including Army helicopters, that helped the men on the ground kill half the enemy force.
Since the Strike Eagle, as the F-15E is known, usually concentrates on OCA and DCA, Polidor said he received six months of CAS training before he deployed to Afghanistan, where he was based at Bagram Air Base. That training was crucial because, in addition to strafing and bombing, PoIlidor had to set his plane up as a communications relay between the JTAC and the other aircraft. His backseater became a JTAC for 19 aircraft. According to his citation for the DFC, Polidor (on his first day of combat), ”took control of the 19 aircraft on scene and orchestrated air strikes from six F-15Es, four A-10s, two AH-64s and a B-1.”
He would not offer an opinion as to whether the A-10 should be retired or not (he is a captain, after all) but he did note that other Air Force fighters simply have to fly much faster to be safe and maintain maneuverability than does the A-10. While that means the F-15 can get to the scene more quickly, it also means it must leave more quickly and cannot fly as low and slow as can the A-10. He said an A-10 could probably execute two strafing runs for each one he can do because of that slower speed and lower altitude.
The circumstances of Polidor’s operation offer a window into just why the Air Force thinks it may be able to replace the A-10 even before the F-35A is available in late 2016. (The Marine Corps F-35B will be available earlier, in late 2015, and the Navy F-35C model by February 2019).
His aircraft executed a complex strafing run of a twisting valley road and dropped two laser-guided bombs and two GPS-guided bombs and did not injure any US or allied solders. The aircraft he and his weapons officer directed killed 72 Taliban, almost half the enemy deaths, a fine demonstration of what Gen. Hix meant when he cited the value of Close Air Support as airborne artillery. The fact that Polidor was able to execute such an array of complex maneuvers on his first day of air combat is testament to the CAS training he received.
So what does all this say about the A-10? Certainly, many of its effects can be duplicated by other, newer aircraft and usually are. Its psychological or morale effect on ground troops — fear for the enemy and jubilation for Americans and our allies — cannot readily be duplicated since the other aircraft do not fly low and slow. The A-10 is more vulnerable to sophisticated anti-aircraft defenses than the other multi-role aircraft (although recent upgrades have improved the odds) and Air Force officials believe it will be too vulnerable within 10 years.
Richard Aboulafia, one of the deans of aerospace analysts at the Teal Group, aptly summed up the A-10s prospects:
“It has faced dangerous moments before, it has faced retirement before, and it’s pulled through. You can make an argument for it either way, it’s not a dumb plane to have around by any means, it’s a very useful plane; the argument is in a time of austerity no service can afford single mission aircraft.”
The Air Force can probably retire the entire A-10 fleet in several years, but neither Congress nor the Army will be completely comfortable with that. But the $3.7 billion the Air Force estimates it could save will be very tempting to harvest, especially once we have largely withdrawn from Afghanistan and the F-35s reach IOC. Our bet: retirement starting in fiscal 2016. That leaves time to educate and mollify Congress and to demonstrate to the Army its soldiers won’t be left without effective protection.
