Royal Navy survey vessel HMS Echo continues search for MH370

Echo was launched at Appledore Shipbuilders, Bideford on 4 March 2002 and commissioned into the Royal Navy on 13 March 2003. Lead vessel in her class (HMS Enterprise is Echo’s sister ship), she was designed to carry out a wide range of survey work, including support to submarine and amphibious operations, through the collection of oceanographic and bathymetric (analysis of the ocean, its salinity and sound profile) data.

On 20 March, 2014, Echo was operating in the Persian Gulf, midway through an 18-month hydrographic surveying deployment, when she was tasked to assist the Royal Australian Navy search for missing Malaysian Airlines flight MH370 in a sector of the Indian Ocean 2,400 km (1,295 nmi) southwest of Perth, Australia.

Echo’s Commanding Officer Commander Phillip Newell said his 60 men and women were giving the search their all. “My ship’s company are working 24/7 to find MH370. They are young, bright and enthusiastic and will step up to every challenge in the search for the missing aircraft. I am immensely proud of them.”

The Australian govt is overseeing search operations from its newly created Joint Agency Coordination Centre. Eight countries are involved in the search.

OTDIH 23 October 1943

70-years ago today…

Großadmiral Karl Dönitz has 95 U-boats at sea. The Battle of the Atlantic was not over.

In the South Atlantic:

U-170, a Type IXC U-boat, KptLt Günther Pfeffer commanding, on its 2nd war patrol, torpedoed and sunk the unescorted Brazilian steam merchant Campos (4,663 GRT) 5-miles south of Alcatrazes Island, Brazil. The crew of 57 and 6 passengers took to the ship’s lifeboats, tragically two of which were struck by the ship’s screw, throwing the occupants to the water. 10 crew members and 2 passengers were lost.

In the Black Sea:

U-23, a Type IIB U-boat, KptLt Rolf-Birger Wahlen commanding, on its 12th war patrol, torpedoed and sunk the Soviet motor merchant Tanais (372 GRT) anchored at Poti, Georgian SSR. The U-Boat was operating in the Black Sea with the 30th U-Boat Flotilla… having been transported overland to Konstanza, Rumania in 1942.

Setting a wartime record:

U-196, a Type IXD U-boat, KKpt Eitel-Friedrich Kentrat commanding, returned to Bordeaux, France… thus completing the longest patrol by any submarine during the Second World War: 256-days from 13 March to 23 October 1943.

Attacked in the Atlantic:

U-190, a Type IXC U-boat, KptLt Max Wintermeyer commanding, on her 3rd war patrol, was surfaced ahead of convoy GUS-18 when attacked by the US Navy Gleaves-class destroyer USS Turner (DD-648). The Turner attacked the surfaced U-boat with her Mk 12 5-inch/38-caliber guns. When the U-190 submerged, the Turner attacked with depth charges… shock waves from which disabled the destroyer’s radar and sound gear. By the time Turner was able to resume her search, U-190 had escaped.

Royal Navy suffers double disaster during Operation Tunnel:

During Operation Tunnel, HMS Charybdis, a Dido-class cruiser commissioned into the Royal Navy in 1941, Captain George Arthur Wallis Voelcker, RN commanding, was sunk off north coast of Brittany, France in position 48º59’N, 03º39’W by 2 torpedoes from the German Elbing-class torpedo boats T-23 and T-27 (not MTBs, but torpedo-armed destroyers). 464 men died (including the commanding officer) and 107 survived.

During the same action, HMS Limbourne (L57), a Hunt-class escort destroyer, Cdr Walter John Phipps, RN commanding, was heavily damaged by German torpedo boats T-22 and T-24. Damaged beyond repair, Limbourne was sunk by gunfire from HMS Rocket (H92) and HMS Talybont (L18).

HMS Westminster conducts ASWEX with USS Dallas

The Royal Navy’s Response Task Force Group was established following the 2010 Strategic Defence and Security Review. The RFTG serves as Britain’s high-readiness amphibious task force and provides a scalable force able to deploy worldwide to meet crises.

HMS Westminster is part of the UK’s Response Force Task Group (RFTG) currently on the Royal Navy’s annual Cougar deployment.

HMS Illustrious, RFA Fort Victoria, RFA Fort Austin, USS Bulkeley and the American Los Angeles Class Submarine USS Dallas also took part in the exercise.

The aims of the exercise is to develop maritime interoperability by exercising Anti-Submarine Warfare tactics with US allies in the challenging sonar environment of the warm and shallow waters of the Gulf region.

The exercise was broken down into three phases. The ships and submarines initially tested acoustic and non-acoustics sensor performance against known positions, gaining useful real life data for the region.

The second phase relied on the ships escorting HMS Illustrious as the Mission Essential Unit (MEU) along a passage whilst evading detection and simulated torpedo attacks by USS Dallas.

In the final phase USS Dallas tried to locate and destroy RFA Fort Austin as the MEU, in a holding box which simulated an anchorage, as the UK and US naval ships provided protection.

Additional helicopter support to the ships was ably provided by the Anti-Submarine sonar dipping Merlins embarked in HMS Illustrious and USS Bulkeley’s Seahawk, with Westminster’s Mark 8 Lynx helicopter providing an additional surface search and weapon carrying capability.

As well as taking turns to practise submarine hunting, the sailors from all ships and the submarine were put through their paces.

One of Westminster’s Anti-Submarine Warfare specialists, Petty Officer Underwater Warfare ‘George’ Linehan said:

“This was an excellent opportunity to work with our close allies in Anti-Submarine Warfare.

“The Royal Navy has again demonstrated how effective a T23 Frigate can be in a multi-national task group”.

Aside from this Anti-Submarine exercise, HMS Westminster has had a busy period since leaving the Red Sea, including Replenishments at Sea (RAS) with the USS Artic and also a rare dual RAS with HMS Illustrious and RFA Fort Victoria.

HMS Westminster’s Commanding Officer Hugh Beard said:

“It has been a busy period for Westminster since leaving the Suez Canal, with invaluable training and cooperation with our key allies in the region.

“We are now looking forward to contributing to the wider maritime security in the Indian Ocean and the Gulf as part of our ongoing mission.”

HMS Westminster is currently conducting counter-terrorism and counter-narcotics patrols in the Gulf region and returns to the UK in 2014.

The Cougar 13 deployment will operate in the Mediterranean, Red Sea, Arabian Gulf, and Horn of Africa. It involves exercising with partner nations, and will show the UK Armed Forces’ capacity to project an effective maritime component anywhere in the world as part of the Royal Navy’s Response Force Task Group, commanded by Commodore Paddy McAlpine OBE ADC Royal Navy.

The RFTG is the United Kingdom’s high readiness maritime force, comprising ships, submarines, aircraft and a landing force of Royal Marines, at short notice to act in response to any contingency tasking if required.

Ladybird Series 606B (People at Work): The Sailor

Remember this? Ladybird’s ‘People at Work’ book on The Sailor. Yours, at the time, for two an’ six. You’ll have to pay a bit more than half-a-dollar for one on ebay these days. I adored the Ladybird books. This is how children used to learn to read and learn a bit about life at the same time. Sorry, I don’t have images of every page.

43 nations have over 600 submarines

At present, 43 nations have over 600 submarines

TNN | Aug 19, 2013, 06.03 AM IST

The INS Sindhurakshak tragedy has brought the focus on the mysterious world of submarines. Here are some interesting submarine facts.

When was submarine first used in war?

By early 18th century, many inventors made several designs of naval vessels that could travel on the surface as well as beneath water. The American Revolution was the first war that witnessed military deployment of such boats. Submarines were also used during the American civil war. Submarines equipped with torpedo became a major factor during the First and the Second World War. According to US navy at present there are 43 countries operating over 600 submarines.

How does a submarine submerge?

One of the most important features of a submarine’s design is the ballast tanks. These tanks could be alternatively filled with water or air depending on the requirement, whether the vessel wants to float on water’s surface or travel underwater. The tanks are filled with air when the submarine is at the surface. To submerge the air is released and the tanks are filled with sea water which makes the vessel heavier.

Submarines maintain a stock compressed air while travelling underwater. This air is used for life support and for filling the ballast tank.

How does a submarine propel?

Most of the today’s diesel submarines work like a hybrid vehicle. A typical diesel submarine has two diesel engines. One engine is used to propel the vehicle when it is on surface while the other is used to charge its batteries. These vehicles can only go underwater after fully charging their batteries. After going underwater they are propelled by battery-powered electric motors. Because of the battery powered propulsion the diesel submarine can stay underwater for a limited period.

A nuclear powered submarine is not based on combustion engine. Unlike diesel subs, a nuclear sub doesn’t need air to burn it fuel and hence it can remain underwater for a much longer period.

How is the underwater navigation done?

Typically, submarines don’t have windows and hence the crew could see outside underwater. When a submarine is near surface then it uses periscope to have the outside vision. Most of the submarine travel much deeper than the periscope depth and the navigation is done with the help of computers. Like any other conventional ship, a submarine navigator is also dependent on regular ocean navigation chart.

The submarine uses Sonar (Sound Navigation and Ranging) to detect target ships.

How is the submarine’s environment controlled to support life?

Modern submarines- nuclear as well as diesel are designed to stay underwater for a significantly longer period. To have a healthy environment for humans a submarine is required to maintain earth like air quality, supply fresh water and maintain suitable temperature. Most of the submarines are equipped with oxygen generator and water purifiers.

These equipments use sea water to generate oxygen as well as produce fresh water. Apart from this the carbon dioxide and moisture is periodically removed to keep the environment healthy.
