#QEaircraftcarriers - On Armistice Day the massive hull of the Royal Navy's newbuild 65,000 tonnes aircraft-carrier HMS Queen Elizabeth, was finally completed with the 'ski-ramp' slotted into place at Rosyth Dockyard, writes Jehan Ashmore.

The facility on the Forth of Fife is one of three Scottish shipyards that despite job losses are to remain open in the UK and continue building warships for the Royal Navy, following recent plans to close the shipyard in Portsmouth in 2014.

The momentous occasion saw the installation of the 130-tonne section ski-ramp which is designed to assist the F35 Lightning IIs to get airborne off the expansive flight deck of the Royal Navy's future flagship.

Only the radar and lifts remain to be lifted into place by 'Goliath' not to be confused with the same namesake given to one of Harland & Wolff's giant yellow cranes. The Scottish 'Goliath' is superior in that the crane is the UK's largest, capable of boaring loads up to 1,000 tons.

The newbuild HMS Queen Elizabeth is the leadship of a pair "QE-Class" aircraft-carriers which is to be followed by HMS Prince of Wales. They will represent the biggest and most powerful surface warships ever constructed for the Royal Navy. HMS Queen Elizabeth after fitting-out and sea-trials is to scheduled to enter service in 2017.

The cost of new aircraft carriers is expected to be almost twice the original estimate in which the according to latest budget, the Ministry of Defence estimates the cost of the two ships at £6.2bn.

The QE –class replace the Invincible-class trio in which the 22,000 tonnes HMS Illustrious (RO6) remains the last in service albeit in the role as a converted helicopter carrier. As previously reported, HMS Illustrious paid a visit to Dublin Port in April and was illuminated in green for the Gathering.

To build the QE –class aircraft carriers which present complexity and challenges requires many skills and experience which led to the establishment of the Aircraft Carrier Alliance which is between BAE Systems, THALES and Babcock.

Of the 37 main sections that were constructed to assemble HMS Queen Elizabeth, yards including Babcock's Marine's north Devon shipyard in Appledore were involved in building sections. The sections were then transported by barge to the newbuild in Scotland.

Babcock won the €99m contract from the Irish Department of Defence to build a pair of OPV's currently under construction also in Devon for the Naval Service. The first of the enhanced 'Roisin' / OPV P90 class L.E. Samuel Beckett (P61) is due for delivery in early 2014.

About Quarter Tonners

The Quarter Ton Class is a sailing class of the International Offshore Rule racing the Quarter Ton Cup between 1967 and 1996 and from 2005 until today.

The class is sailed by smaller keelboats of similar size and is likely the world's most-produced keelboat class.

The Ton, Half, Quarter, etc. 'classes' were each given a 'length' and yacht designers had almost free rein to work the hull shapes and measurements to achieve the best speed for that nominal length.

The Ton Rules produced cranky and tender boats without actual downwind speed. Measurement points created weird, almost square hull shapes with longish overhangs.

They were challenging to sail optimally and lost value very quickly as any new wrinkle (e.g. 'bustles') to take advantage of the rule made older boats very quickly uncompetitive.

Although its heyday was 30 years ago, the boat class continues to make its presence felt by holding its own in terms of popularity against some fern race fleets.
