Libya : Harrier Versus Tornado




"The Tornados have delivered [MBDA] Storm Shadows to penetrate hardened buildings and the dual-mode Brimstone,neither of which could have been delivered by the Harrier."

"I am not knocking the Harrier,just those who have,often willfully,overstated its relative utility in this scenario,"

"In operations such as Ellamy,on the periphery of Europe,the access,basing and over-flight restrictions that would necessitate carrier strike do not apply.

 There is simply no comparison in terms of platform capability,time on station or versatility between Tornado GR4s operating from a well-found NATO airfield in Italy and Harriers operating from a CVS*."

*A Royal Navy aircraft carrier.

Air Chief Marshal Dalton,the current head of the British Royal Air Force (R.A.F.),and a former Tornado pilot,may not have read our previous piece "What To Cut: Typhoon,Harrier And Nimrod Versus Tornado And F.S.T.A.".


If he had,he would know that Brimstone was due to be cleared on the Harrier as part of the "Capability D" upgrades.


Harrier had already flown trials with Brimstone at the time the Chief of the Air Staff (a former Tornado pilot) made this comment.


At the time of the Strategic Defece and Security Review it was often claimed that the Harrier could not carry Brimstone.

This was cited as one of the reasons for retaining the Tornado instead of the Harrier.

This is what the Royal Air Force's own website had to say on the matter:

"The aircraft (Harrier G.R.9) is also expected to be fitted to carry the advanced Brimstone fire and forget anti-armour missile."







It was also often claimed that the Harrier should be retired because it could not fire the Storm Shadow cruise missile.

Here is the view of one commentator,Thinkdefence:

"Storm Shadow is very large and heavy.

 Because of asymmetric loading and release issues,dropping one of these from a wing pylon would be a serious issue to overcome,even for a Tornado,the Tornado carries them on the fuselage hardpoint for this reason.

A Harrier does not have the ability to do this because of under fuselage clearance;wing pylon mounting would be the only option.

This means those asymmetric release issues become more pronounced and because of the length of the missile and relative size of the Harriers wing it is difficult to see how it would be carried on a wing pylon without some additional costly modification."


Here is the official position from Nick Harvey,Minister of State for the Armed Forces in Parliament on the 18th of July 2011:

"The Harrier aircraft was withdrawn from service on 15 December 2010.

Prior to its withdrawal,it had an operational emergency clearance to operate Baseline Brimstone.

 In order for the Harrier to use Dual Mode Seeker Brimstone,we would have had to extend the provision for the weapon and conduct a full trials programme on Harrier.

Although capable of carrying Storm Shadow,Harrier was not cleared to do so when it was withdrawn from service."


Harrier was capable of carrying Storm Shadow,numerous official statements confirm that.

Yet it is still common to hear claims to the contrary.

Full clearance for Storm Shadow to fly on the Harrier fleet was cancelled by the Royal Air Force in a "cost cutting exercise".

Harrier could also have carried a pair of Storm Shadows to a considerable unrefuelled combat radius.

Although some commentators seem to think otherwise,here is a comment from Thinkdefence:


"You also have to ask if with a pair of Storm Shadows, plus drop tanks, plus ECM and self defence systems a Harrier would have got off the deck at all, unless of course it would have had to take off almost empty of fuel and get refuelled in the air."

United States Navy figures (page 7 of this document) give the Harrier a Hi-Lo-Hi combat radius of 302 miles with 12 500 pound bombs (6,000 pounds total weapon load),strakes and no external fuel tanks,with no aerial refuelling.

A Harrier with 2 2,860 pound Storm Shadows (5,720 pounds total weapon load),strakes and no external fuel tanks tanks should have a Hi-Lo-Hi combat radius greater than 302 miles due to the slightly lower weight and drag.






British aircraft carriers have often operated around 50 miles off a hostile coast during combat operations,including during the Invasion of the Suez Canal Zone in 1956 and the invasion of Iraq in 2003.









It is reasonable to assume that a British aircraft carrier would launch Storm Shadow armed harriers from about 50 miles off the Libyan coast.

This would allow the Harriers to launch Storm Shadow missiles 252 miles or more inside Libyan territory.


Storm Shadow has an officially quoted "range in excess of 250km (156 miles)",a Harrier would be able to deliver 2 Storm Shadow missiles to targets beyond a radius of 458 miles from it's aircraft carrier.

This allows a Harrier to engage targets over 408 miles in side Libya from an aircraft carrier 50 miles off shore,with noaerial refuelling.



Royal Air Force Tornados launched Storm Shadow attacks on Libya from R.A.F. Marham,1,502 miles from Tripoli.



The Tornado's Hi-Lo-Hi combat radius is widely quoted as 863 miles with an unspecified weapon load.

This is far short of what would be required for a Tornado based at R.A.F. Marham to fire Storm Shadow missiles at targets in Libya without aerial refuelling.



Marham's Tornados required 4 aerial refuellings just to deliver 2 Storm Shadow missiles each against targets in Libya.

Each sortie involved an 8 hour,3,000 mile round trip.


Even with this vast amount of tanker support the Marham based Tornados were only ably to cover a small portion of Libyan territory.



With no aerial refuelling support at all a carrier based Harrier can range across much of Libya's territory while carrying a pair of Storm Shadow missiles.

Tornados launched 2 Storm Shadows each on the fringes of Libyan territory and needed 4 aerial refuellings to do that.


The Harrier could provide coverage with the Storm Shadow missile far superior to that of the Tornado.

It would also require no aerial refuelling.



"In operations such as Ellamy,on the periphery of Europe,the access,basing and over-flight restrictions that would necessitate carrier strike do not apply."

In order to attack Libya the Marham based Tornados required overflight rights from at least 2 countries and possibly many more depending on their route.

Each of these countries would have the potential to disrupt combat operations at any time as has happened on many occasions in the past.

Including during current operations in Afghanistan.

Harriers based on an aircraft carrier in international waters off the Libyan coast do not require over flight rights from any country.


Land based Tornados required Host Nation Support from Italy.

But Italy was opposed to the creation of a No Fly Zone (N.F.Z.) over Libya until the United Nations adopted Security Council Resolution 1973 on the 17th of March 2011.


Which is why Royal Air Force Typhoons did not begin flying sorties from Gioia Del Colle until the 21st of March 2011,2 days after a Royal Navy submarine had fired cruise missiles in to Libya.

The submarine was able to pre-position it's self before combat operations began as it did not rely on host nation support.

The first Typhoon combat sortie from Gioia Del Colle was the following day but the Typhoons could not conduct ground attack missions.

Tornados,which could,arrived in Italy only on the 22rd of March 2011,3 days after the Royal Navy had begun combat operations against Libya.



R.A.F. VC10 tanker aircraft and Sentry surveillance aircraft initially operated from the British base at Akrotiri on Cyprus.

This required them to spend approximately 4 hours in transit on each sortie.


To reduce this waste of flying hours they were sensibly relocated to a closer Italian base at Trapani-Birgi on Sicily.

Trapani-Birgi is a civilian airport,348 miles from Tripoli,which is also used by military aircraft.



Unfortunately one of it's main civilian users,Ryanair,complained that it's passengers were being inconvenienced by the Royal Air Force presence.

Consequently the Italian authorities were about to evict the R.A.F. from Trapani until preempted by the sudden end of combat operations.


Malta refused to grant host nation support to military aircraft involved in attacks on Libya.

But it did grant over flight rights.

Nevertheless,combat aircraft,including Royal Air Force Tornados,were sometimes forced to land at Malta International Airport.

When your air base is 582 miles away in Italy and you don't have enough fuel to get there,you have to land somewhere.

This would not have been a problem for a Harrier who's home was an aircraft carrier 50 miles off the Libyan coast.

Fortunately the Maltese government did not impound these aircraft  as the Brazilians did with a Vulcan bomber which was forced to divert there during the Falklands War in 1982.


In total the Royal Air Force used 6 airfields to conduct operations against Libya.

Of these,3 were on British Bases in the United Kingdom (R.A.F. Marham and R.A.F. Brize Norton) and Cyprus (R.A.F. Akrotiri).

Italy provided 2 more bases,one of which was at a semi-civilian airport (Trapani-Birgi and Gioia Del Colle).

Malta International Airport  provided an emergency landing site for combat aircraft which could not make it 582 miles back to Gioia Del Colle from Libya.


Had the United Kingdom deployed a catapult equipped aircraft carrier,none of these bases would have been necessary.


A fleet of Hercules and Globemaster transport aircraft was needed to deploy Royal Air Force units to their overseas bases.

These are the "replenishment vessels" of the Royal Air Force delivering tools,support equipment,parts and ordnance to bases in Italy and Cyprus.

But these aircraft are far more expensive to buy and operate than ships and an aircraft carrier would not require their support.


The RAF's No 2 (Mechanical Transport) Squadron transported 1,680 tonnes of kit down to the airfield at Gioia del Colle,including generators,air start trolleys,drop tanks,hydraulic rigs and weapon loaders for the Typhoons and Tornados.

An aircraft carrier would have all of this equipment on board,eliminating the need for transport aircraft or trucks to bring it in to theatre.



"There is simply no comparison in terms of platform capability,time on station or versatility between Tornado GR4s operating from a well-found NATO airfield in Italy and Harriers operating from a CVS*."

There are many factors which influence the combat and endurance of a combat aircraft.

These include weapon load,fuel load,runway length,temperature,altitude,speed and flight profile.
The chart above is from an official United States Navy document on the AV8B,the American version of the British Harrier G.R5/7/9 aircraft and gives us a good idea of that aircraft's capabilities.

Unfortunately such specific information is often unavailable and we have to deal with far less well defined figures.


The Royal Air Force claims that the Tornado has a combat radius of 460 miles (400 nautical miles) on a Lo-Lo-Lo flight profile with an unspecified weapon load.

This is not sufficient for a Tornado based at Gioia Del Colle to attack targets in Libya without aerial refuelling.



The Harrier G.R.9 has a Lo-Lo-Lo combat radius of 287 miles (250 nautical miles) with an unspecified weapon load according to the Royal Air Force.

Unlike the Tornado,a Harrier on a Lo-Lo-Lo flight profile can attack targets in Libya,with no aerial refuelling,when flying from an aircraft carrier 50 miles off the Libyan coast.




These Royal Air Force figures demonstrate that,on a Lo-Lo-Lo flight profile,the range and endurance of the carrier based Harrier are far superior to those of the Tornado for operations over Libya.


Various official and unofficial sources say that the Tornado has a Hi-Lo-Hi combat radius of 863 miles with an unspecified weapon load.



This allows only limited loiter time over Northern Libya which is why Tornados required several aerial refuellings on a typical 5.5 hour mission over Libya.



The Royal Air Force credits the Harrier with a radius of 402 miles (350 nautical miles) at medium level,again with an unspecified weapon load.



This gives the Harrier more time on station over Libya than a Tornado on a Hi-Lo-Hi flight profile with no aerial refuelling.



The above picture shows a typical weapon load for a Harrier on combat operations in Afghanistan.

It carries 2 500 pound bombs,2 rocket pods,a targetting pod,a reconnaissance pod and 2 drop tanks.


The closest configuration to that on the chart above is for a Harrier with 4 1,000 pound Mark 83 bombs and 2 300 Gallon drop tanks.


According to these United States Navy figures a Harrier would have a Lo-Lo-Lo combat radius of 363 miles (316 nautical miles) with this weapon load.

This allows the Harrier to attack targets up to 313 miles inside Libya with no aerial refuelling when based on an aircraft carrier 50 miles off shore.


Unlike a Tornado based at Gioia Del Colle,which cannot attack targets in Libya without aerial refuelling.


On a Hi-Lo-Hi flight profile the same aircraft has a combat radius of 661 miles.

That is enough to attack targets throughout most of Libya with no aerial refuelling.

That range could also be traded for endurance in the coastal areas.



Again,the Harrier offers range and time on station far superior to the Tornado  when flying a Hi-Lo-Hi flight profile.



"There is simply no comparison in terms of platform capability,time on station or versatility between Tornado GR4s operating from a well-found NATO airfield in Italy and Harriers operating from a CVS*."

Time On Station Versus Flight Time


The above graph shows time on station over Libya versus total flight time for a Tornado based at Gioia Del Colle in Italy and a Harrier based on an aircraft carrier 50 miles off the Libyan coast.

It assumes that both aircraft transit to the combat area at a speed of 480 miles per hour or 8 miles per minute.

At this speed the Harrier has a transit time of 12.5 minutes while the Tornado has a transit time of 145.5 minutes.

Which means that the Tornado has to fly for over 145.5 minutes to spend any time on station over Libya at all,while for any sortie length beyond that the Harrier generates 133 more minutes on station per sortie than the Tornado.

During combat operations over Libya Tornados averaged about 5.5 flight hours per sortie which gives 184.5 minutes on station over Libya on each sortie at a transit speed of 480 miles per hour.

On a 5.5 hour sortie the carrier based Harrier would spend 317.5 minutes on station over Libya.

It would take 4.5 such Harrier sorties per day to keep one Harrier on station over Libya for 24 hours.

In contrast the land based Tornados would need to fly 7.8 daily sorties to keep one Tornado on station over Libya for 24 Hours.

During combat operations over Libya,Royal Air Force Tornados and Typhoons averaged about 9 sorties per day.

It is likely that the time on station generated by these sorties could have been generated by just 5 daily carrier based Harrier sorties.
