Canadian Surface Combatant



BAE Systems have won the Canadian Surface Combatant competition,following their recent win in Australia with the Hunter Class variant,potentially increasing production of the Type 26 Frigate family to around thirty two ships,with an additional twenty in prospect if they also win the United States' Navy F.F.G.(X.) competition where two of the contenders are the F.R.E.M.M. and F100 frigates which lost the Australian and Canadian competitions.

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)"

More Lies Damned Lies And Aircraft Carriers


We have discussed in another thread how some members of the British Royal Air Force have difficulty distinguishing facts from fiction whenever the phrase "aircraft carrier" is mentioned.

Here we will consider further some more oft repeated "facts" about aircraft carrier operations.


Members of the junior service claim that the United State's Navy's aircraft carriers spend little time on station in the Northern Arabian Sea because they have to keep returning to port to replenish.

They further suggest that the carrier's contribution to the air war over Afghanistan is so insignificant that if they were not there,nobody would notice.


Let us see if these claims bear any relationship with reality.

The last American aircraft carrier to be relieved on station in the Arabian Sea was the United States Ship (U.S.S.) Harry S. Truman (C.V.N.75).



U.S.S.Harry S. Truman joined U.S.S. Dwight D. Eisenhower (C.V.N. 69) on station in the Northern Arabian Sea on the 26th of June 2010.



On the 29th of June 2010 U.S.S. Harry S. Truman flew her first combat sorties as part of Operation Enduring Freedom over Afghanistan.

Sustained by at sea replenishment,U.S.S. Harry S. Truman continued to fly combat sorties over Afghanistan for the next 36 days until the 4th of August 2010.

On the 5th of August 2010 the U.S.S. Harry S. Truman made port at Jebel Ali in the United Arab Emirates.



There,her crew were able to enjoy a brief period of rest and recreation for 3 days until the 8th of August 2010.

U.S.S. Harry S. Truman was back on station in the Northern Arabian Sea flying combat sorties over Afghanistan on the 9 th of August 2010.



She continued to fly combat sorties over Afghanistan,sustained only by under way replenishment,for 31 days until the 8th of September 2010.

On the 9th of September 2010,U.S.S. Harry S. Truman again put in to port at Jebel Ali in the United Arab Emirates.

There her crew again enjoyed 3 days rest before departing on the 12th of September 2010.

On the 13th of September 2010,U.S.S. Harry S. Truman was back on station in the Northern Arabian Sea conducting combat operations over Afghanistan.



These combat operations continued for 36 days until the 19th of October 2010,the carrier was replenished at sea throughout this period.




U.S.S. Abraham Lincoln arrived in the Northern Arabian Sea on the 17th of October 2010 and began flying combat sorties over Afghanistan on the 18th of October 2010.


Lincoln spent 72 days at sea before putting into Bahrain for 3 days of well earned rest from the 18th to the 21st of November 2010.




The U.S.S. Harry S.Truman then moved to the Arabian Gulf.

The U.S.S. Harry S.Truman's crew spent 4 days resting when the ship put in to Khalifa Bin Salman Port at Hidd in the Kingdom of Bahrain from the 28th of October 2010 until the 1st of November 2010.



For the 25 days from the 2nd of November 2010 to the 27th of November 2010 she was again flying combat sorties over Afghanistan supported by at sea replenishment.




The U.S.S. Harry S. Truman then left the operational area in the Northern Arabian Sea,entering the Red Sea on the 28th of November.


Between U.S.S Harry S.Truman flying her first combat sortie over Afghanistan on the 29th of June 2010 and flying her last on the 27th of November 2010 is a period of 151 days.


She spent just 10 days in port over this period and 141 days at sea sustained by replenishment vessels.


There was a United States Aircraft carrier flying sorties over Afghanistan for 145 of these 151 days.


There were 2 American aircraft carriers conducting flying operations for 37 of those 151 days.


The claim that American aircraft carriers spend little time on station in the Northern Arabian Sea because they must return to port to replenish is clearly not true.


The United States Navy tends to publish the number of sorties generated by it's aircraft carriers when those ships return home.


The U.S.S. Harry S Truman has not returned home yet,she is currently in Greece.

Consequently the number of sorties she flew over Afghanistan have not been released yet.



"Since arriving in the 5th Fleet A.O.R. (Area Of Responsibility) June 29,aircraft assigned to C.V.W. 3 (Carrier Air Wing 3) completed more than 3,300 aircraft sorties and logged more than 10,200 flight hours,with more than 7,200 of those hours in support of coalition ground forces in Afghanistan."


Those figures cover a period of 88 days giving an average of  37.5 sorties and 116 hours flown per day including 82 flight hours flown in support of ground troops in Afghanistan.


During this period Britain's XIII Squadron of the Royal Air Force was operating in Afghanistan for the 90 days from the 19th of July 2010 to the 16th of October 2010.

They flew 1,850 hours during this period,an average of just under 21 hours a day and "a Tornado GR4 record for Operation Herrick".

The U.S.S. Harry S. Truman's aircraft flew 4 times as many hours of close air support in Afghanistan each day as the Royal Air Force Tornados of XIII Squadron managed.

Unfortunately figures for the total number of sorties flown by XIII Squadron in Afghanistan do not appear to have been released (weekly figures suggest about 5-6 sorties a day) but more detailed information about the squadron which preceded them is available.

Between the 14th of April 2010 and the 18th of July 2010,II (Army Co-operation) Squadron was operating in Afghanistan.

Over this period of 96 days they flew 515 sorties totalling 1680 flight hours,an average of just over 5 sorties per day and  17.5 flight hours a day (they dropped 5 Paveway IV bombs and fired a total of 4 Brimstone missiles over the 96 day period). 

These figures make an interesting comparison with the following extract from A Day In The Navy October 13th 2010


"USS Harry S. Truman (CVN 75) conducts a morning replenishment-at-sea with USNS Big Horn (T-AO 198) and USNS Sacagawea (T-AKE 2).

Elements assigned to Carrier Air Wing (CVW) 3 conduct 25 sorties (149.4 flight hours) in support of Operation Enduring Freedom."


Despite conducting an under way replenishment, on the 13th of October 2010 the U.S.S. Harry S. Truman flew 5 times as many combat sorties and more than 8 times as many flight hours over Afghanistan as the Royal Air Force II Squadron Tornados averaged per day and 7 times as many flight hours as XIII Squadron averaged per day.

The following figures cover November 2010,both the U.S.S. Abraham Lincoln and the U.S.S. Harry S.Truman were on station in the Northern Arabian Sea for most of this month:


"The Abraham Lincoln Carrier Strike Group (CSG) flew 1,571 sorties for 4,001.5 hours of flight time supporting Operations Enduring Freedom and New Dawn;the Harry S. Truman CSG completed 480 combat sorties and 2863.3 flight hours in support of Operation Enduring Freedom."


In November 2010 the two American aircraft carriers between them averaged 68 sorties per day and 229 flight hours per day in support of operations in Iraq and Afghanistan,approximately 11 times as many as the Royal Air Force Tornados contibuted to operations in Afghanistan.

It is interesting to note that Royal Navy aircraft carriers have often generated higher sortie rates than American carriers on combat operations.

The new Queen Elizabeth class aircraft carriers should easily be able to match or exceed the performance of the American carriers in Afghanistan.

The claim that American aircraft carrier's 
contribution to operations in Afghanistan is
 so small that if they were not there nobody
 would notice does not stand up to scrutiny.

The United States Navy delivers a large proportion of the combat air power in Afghanistan,typically generating about 25-30% of close air support sorties in the land locked country.

In contrast the Royal Air Force generates only about 5% of the combat sorties flown in Afghanistan each day.

If they were not there,would anyone notice?
