Defence skills shortage makes us an easy sub target

AUSTRALIA is vulnerable to attack from submarines as concerns mount over dodgy military equipment and a lack of skilled undersea warfare operators.

View Larger Map
The nation is dangerously exposed at a time when 100 new submarines are due in service with regional navies, including those of China, India, Pakistan, Russia, Malaysia, Singapore and Indonesia, experts say.

China already has more than 60 submarines with others on the way, Russia's Pacific fleet is 22 strong and India is boosting its 16-boat fleet.

The erosion of anti-submarine warfare is due to:

SYSTEM failures on Collins class submarines.

POOR vessel-mounted sonars.

OBSOLETE torpedoes.

DELAYS to ship upgrades.

Australian Strategic Policy Institute defence expert Andrew Davies said the lack of equipment was symbolic of wider problems.
"Detecting a submarine at long range involves a lot of interpretation and is not a skill you can teach overnight," he said.

Pak gets two upgraded P-3C Orion aircraft from US

ISLAMABAD (BNS): Pakistan Navy has recently received two upgraded P-3C Orion maritime surveillance aircraft from the US.



Lockheed Martin, which has developed and refurbished the aircraft, had delivered the first P-3C to Pakistan in October, 2009. The second aircraft was delivered on January 7 this year, the company announced on Thursday. It is upgrading a total of seven such aircraft for Pakistan.



The upgraded maritime patrol aircraft are to be supplied to the country as per a 2006 contract with the US Government under its Foreign Military Sales programme.



The aircraft are equipped with enhanced communications, electro-optic and infrared systems, data management, controls and displays, mission computers and acoustic processing, Mike Fralen, director for Lockheed Martin Mission Systems and Sensors' maritime surveillance programmes, said.

Lockheed Martin has delivered its second of seven refurbished P-3C maritime patrol and surveillance aircraft to the Pakistan navy.

Handed over at the US Navy's NAS Jacksonville site in Florida on 7 January and subsequently flown to Pakistan, the aircraft follows an earlier refurbished example that was delivered in October 2009.

Carrying the service registration 87, the latest aircraft is drawn from a 2006 contract placed via the US government's Foreign Military Sales framework. This covers the conversion of ex-USN Orions, with Lockheed upgrading their mission equipment and providing maintenance work.

Dutch military receives first NFH maritime helicopter

NH90’s naval version sees delivery to first customer



As the Dutch Ministry of Defence (MoD) confirmed shortly before Christmas, the Dutch Armed Forces has taken delivery of the first NATO Frigate Helicopter (NFH), the naval version of NHIndustries’ NH90. However, this first helicopter (designated NNLN03), from a total order of 12 NH90 NFH for the Netherlands, is not yet ready to be deployed in operational service, according to Aviation Week & Space Technology. Rather, it will undergo extensive testing and evaluation by the Dutch project office, which will assess whether the helicopter meets its previously agreed requirements.

As the Dutch MoD explains, NNLN03, which was handed over at the AgustaWestland plant in Italy on 23 December 2009, is a temporary so-called Meaningful Operational Capable (MOC) configuration, meaning is does not meet all contractual specifications of the final version. Nevertheless, it can immediately be used for crew training and basic coastal surveillance operations, while NHIndustries works towards completing development of an operationally ready, production standard aircraft.

RAF's Nimrod plane fleet withdrawn in defence cuts


A Nimrod MR2 surveillance plane

The RAF’s fleet of 11 Nimrod surveillance aircraft, one of which catastrophically burst into flames killing 14 servicemen in Afghanistan in 2006, is to be withdrawn from service by March next year as part of a range of defence cuts announced today.

Bob Ainsworth, the Defence Secretary, denied that the decision to axe the Nimrod Mark 2s 12 months earlier than planned had anything to do with the crash of Nimrod XV230, which was caused by leaking fuel, and he insisted it was still safe to fly. He told the Commons the decision was purely for financial reasons.

He said the decision was unconnected to the devastatingly critical official report published in October by Charles Haddon-Cave QC, who accused the Ministry of Defence of sacrificing safety to save money on maintenance of the Nimrod fleet. Several senior military officers were criticised in his report.

However, Mr Ainsworth also announced that the programme to introduce a replacement, the Nimrod MRA4, was going to be delayed. With the Mark 2s scrapped by the end of March, this will leave a capability gap, defence sources confirmed.

The first MRA4 - one of nine ordered - will be delivered to RAF Kinloss in Morayshire - home of the Nimrods - in February but it will not be operational for a long time because the crews will have to carry out lengthy flight training. “It’s a brand new aircraft, so it will take time,” a defence official said.
One of the principal roles of the Nimrod anti-submarine-warfare and surveillance aircraft is to protect Britain’s nuclear ballistic-missile submarine deterrent as it leaves Faslane on the Clyde for patrols in the North Atlantic and Antarctic.

The defence sources said that the protection of the deterrent would have to be left in the hands of the Royal Navy, using hunter-killer nuclear-powered submarines.

The decision on the Nimrod Mark 2s and its replacement will have a considerable impact on the personnel at RAF Kinloss. There are currently 1,600 RAF staff based there, and a proportion of them, especially the engineers, will be displaced to other bases to work on different aircraft.

RAF sources said there were no plans to make any of the Kinloss staff redundant.
Although Mr Ainsworth emphasised that the thrust of the “savings” would be to provide more funds - £900 million - for Afghanistan, the switching of resources will mean that the defence support services will suffer.

The RAF will lose one Harrier squadron and probably a Tornado GR4 squadron although the latter's axeing will be delayed until next year’s strategic defence review. Four of the five Harrier squadrons are based at RAF Cottesmore in Leicestershire, a legendary wartime airfield, and this location is now earmarked for closure. The remaining Harriers will be based at RAF Wittering in Cambridgeshire.

The MoD has not ruled out RAF redundancies, although initially cutbacks will be achieved through natural wastage and a slowing of recruiting. Future redundancies are likely to fall on the staff based at Cottesmore. The base opened in 1938 and early bombing raids were carried out against German troops advancing through Belgium and France.

Andrew Brookes, director of the Air League, warned today that the MoD was once again engaged in trying to save money in the short-term but could expect greater costs in the long term. He said axeing Harriers and Tornados would not save money because they were worth nothing, and delaying the Nimrod MRA4 would add to the spiralling costs of the programme.

This week, the National Audit Office took the MoD to task for making a short-term saving of £450 million on the new Queen Elizabeth class aircraft carrier project by delaying the building programme - only to find that in the long term the cost would rise by £674 million.

The extra money for the frontline will come out of the MoD’s budget instead of Treasury reserves which normally finance operations in Afghanistan, because the new orders for - among other things - more Reaper unmanned spy planes, better body armour and more night-vision goggles and improved communications for special forces are intended to be long-term capability improvements.

Mr Ainsworth also confirmed the planned purchase of 22 more Chinook helicopters and another C17 Globemaster transport aircraft for the RAF. However, the first ten Chinooks will not be ready for operational service for another three or four years, by which time the British combat mission in Afghanistan could be winding down.

Liam Fox, Shadow Defence Secretary, said: “Our defences are being cut, not as a response to a diminished threat – if anything the threat is increasing. The Government that’s had four defence secretaries in four years, one of them part-time, is now cutting capability as a result of catastrophic economic mismanagement. Our brave Armed Forces are paying for Labour’s incompetence.”
“The new Chinook helicopters are of course welcome, but this decision would not have been necessary if the Prime Minister had not, against all advice, cut £1.4 billion from the helicopter programme in 2004,” Dr Fox said.

“But for his failure to understand the Armed Forces, those Chinooks could have been on the frontline today, saving the lives of our brave soldiers. Instead, they will not be available until at least 2013 by which time, according to the Prime Minister, we should have substantially transferred security responsibility to Afghan national forces.” (@timesonline)

GLINT in the eye: NURC explores novel autonomous concepts for future ASW

The La Spezia-based NATO Undersea Research Centre (NURC) has completed a major trial, known as GLINT09 (Generic Littoral Interoperable Network Technology), to investigate the exploitation of autonomous unmanned vehicles (AUVs) as part of a future anti-submarine warfare (ASW) operational construct.

NURC's Ocean Explorer, used as the primary data collecting platform and behaviour demonstrator for the GLINT09 experiment, was configured with a multiple octave BENS towed array and the TOSSA onboard source. (NURC)

The experiment, conducted in mid-2009, is judged to have been an important step towards the long-term goal of a fully functioning collaborative ASW system. NURC is planning to conduct a networked wide-area system demonstration in the 2011-12 timeframe, with the expectation that a deployable capability could be operational in the period 2020-25.

Navy to get three CN-235 surveillance aircraft

The Defense Ministry signed a contract Friday with state aircraft producer PT Dirgantara Indonesia (DI) to procure three CN-235-220 Maritime Patrol Aircraft (MPA) for the Navy to be delivered in two years.

The US$80 million contract was signed by PT DI president director Budi Santoso and the director general of defense facilities at the ministry Vice Marshal Eris Herryanto at the closing ceremony of a national workshop to revitalize the Indonesian defense industry.



Attending the ceremony were Defense Minister Purnomo Yusgiantoro, State Minister for State Enterprises Mustafa Abubakar, Indonesian Military (TNI) chief Gen. Djoko Santoso, and National Police deputy chief Comr. Gen. Makbul Padmanegara.

The officials signed a joint agreement on using domestic defense industry products to fulfill TNI and National Police needs.

“We are committed to procure domestic weapon systems,” Purnomo said.

Meanwhile, Budi said in a  media statement that the patrol aircraft had sensors to carry out surveillance and targeting missions. They are also ready for future anti-submarine warfare capabilities.

“The three aircraft are the first batch of six needed to fulfill a Minimum Essential Force concept while ideally the Navy should have 16 patrol aircraft,” he said.

Navy chief spokesman Commodore Iskandar Sitompul told The Jakarta Post the Navy currently was operating three smaller NC-212 MPA, procured from PT DI in 2007.

The Air Force also operates a CN-235-220 MPA similar to the Navy’s.

When asked whether there would be overlapping missions between the Navy and the Air Force, Navy chief of staff Vice Adm. Agus  Suhartono said it was not the case.

“Our aircraft missions are more tactical such as for firing and acquiring target data [for our warships],” he told the Post at the sideline of the ceremony.

“Meanwhile, the Air Force missions are more strategic.”

Budi said while both Navy and Air Force versions used French-made Thales systems, they have different specifications.

“The Navy version is looking downward with its sensors on the belly of the aircraft while the Air Force version is looking upward with its sensors in the nose of the aircraft,” he told the Post.

“The Navy version is capable of, tracing small contacts on the sea surface such as the retracted periscope of a submarine, while the Air Force is capable of tracing aircraft.”

Budi said the Air Force’ CN-235-220 MPA managed to track an Australian P-3C Orion surveillance aircraft well inside Indonesian territorial waters during a test flight along Java’s  southern coast.

He added another reason to have the French Thales system for the Navy’s patrol aircraft was so they could communicate with four Dutch-made SIGMA corvettes which are also using the Thales system.

PT DI is currently working on four CN-235-110 MPAs for the South Korean Coast Guard in a contract worth $96 million and is involved in upgrading Turkish CN-235s  for maritime patrol and anti-submarine warfare roles in a contract worth $30 million.

Meanwhile, state shipbuilder PT PAL Indonesia signed a memorandum of understanding (MoU) with state oil and gas producer PT Pertamina to design, construct, maintain and repair vessels.

The MoU was signed by PAL president director Harsusanto and Pertamina president director Karen Agustiawan.

“It is Pertamina’s commitment to develop synergy between state-owned enterprises with a mutual benefits principle,” Karen said.(Original News)
