The Cost Of A Catapult



Some time ago in our post titled "Why Catapults Are Cheaper",we said the following:


"The cost of a British electromagnetic catapult system from Converteam is not public knowledge so we can but mention it but prices for the American system are known."


We may now know how much Converteam's catapult costs.

According to this week's Sunday Times newspaper,Converteam have offered to build a land based full scale prototype electro magnetic catapult and a ship set (2 catapults) for a Queen Elizabeth class aircraft carrier at a cost of £140 Million.

This compares very well with the published cost of the American electro magnetic catapult system which we also covered in our earlier post:


"The cost of the Electro-Magnetic Aircraft Launch System (E.M.A.L.S.) ship set for the same vessel is up to $573 Million (£370 Million*).

That is for a set of four catapults,enough for both new British aircraft carriers."


The American system comes in at an average of £92 Million per catapult (a more recent document suggests £105 Million per catapult) versus an average of £47 Million per catapult for the British system if the Sunday Times report is correct.


It would be interesting to know how the price of British arresting gear (made by MacTaggart Scott,inventors of the steam catapult) compares to that of the American Advanced Arresting Gear which costs £66 Million per set.

Electro Magnetic Aircraft Launch System Launches It's First Aircraft


There are those who have suggested that electro magnetic catapults are a high risk technology which will not be ready in time for Britain's Queen Elizabeth class aircraft carriers.

We have disagreed with this point of view in an earlier post.

For some time now,we have been waiting for the American Electro Magnetic Aircraft Launch System (E.M.A.L.S.) to conduct it's first aircraft launch.

With all the excitement at this time of year we almost missed it.

Here it is:



"LAKEHURST,N.J. (Dec. 16, 2010)

The Navy launches the first aircraft,an F/A-18E Super Hornet,from the Electromagnetic Aircraft Launch System (EMALS) at Naval Air Systems Command,Lakehurst, N.J..

The Navy has used steam catapults for more than 50 years to launch aircraft from aircraft carriers.

EMALS is a complete carrier-based launch system designed for Gerald R. Ford (CVN 78) and future Ford-class carriers.

Newer,heavier and faster aircraft will result in launch energy requirements approaching the limits of the steam catapult,increasing maintenance on the system.

The system's technology allows for a smooth acceleration at both high and low speeds, increasing the carrier's ability to launch aircraft in support of the warfighter.

EMALS will provide the capability for launching all current and future carrier air wing platforms from lightweight unmanned aerial vehicles to heavy strike fighters.

The first ship components are on schedule to be delivered to CVN 78 in 2011. (U.S. Navy video/Released)"
