When it comes to transporting troops to/on a battlefield there is always one vehicle that comes to mind, the Chinook but there may be a new contender for this role: the V-22 Osprey.
The iconic and unique tilt-rotor design of the Osprey gives it the take off and landing potential of a helicopter but the flight characteristics of a plane; it truly is the best of both worlds.
There is debate about whether a purchase of Ospreys would be an enhancement to the UK’s capabilities or just an expensive replacement for the perfectly good Chinook.
Though while it is currently a moot debate as the funding is just not present to purchase a fleet of Ospreys, it is always worth considering potential options.
In a straight up comparison it is unclear which if the two aircraft is superior, as while the Osprey can fly further, faster and higher, it flies at almost double the cost of the Chinook as well as having half the troop carrying capability.
As a Chinook can carry up to 55 troops in one load while the Osprey would top out at 32 but that being said a Chinook does not usually carry 55 troops at a time.
But it is all well and good to be able to carry 55 troops but a Chinook could only take them approximately 200 nautical miles, as it has a maximum range of 400 nautical miles.
Whereas the Osprey has a maximum range of 879 nautical miles meaning it could transport troops just shy of 400 miles after take off; so the question is raised, is it more important to have more troops with a shorter range or less troops being deployed further?
Though the answer to that would lie with the operation that was to be undertaken as in combat everything changes and it can change quickly; so speed can be of the utmost to extract for reinforce troops.
Here the Osprey comes out on top again with a maximum speed of 275 knots (316 mph) compared to the Chinooks 170 knots (196 mph), so the Osprey could always get to the designated point quicker.
Yet this all comes at an extra cost, the Osprey costing a whooping $72 million (£52 million) per aircraft compared to the $39 million (£30 million) for a Chinook. But the purchase price is just the start as the operating costs are vastly different.
An Osprey costs $11,000 (£8500) per hour to fly, compared to just $4,600 (£3500) for a Chinook yet it is worth noting for all the extra money the Osprey does have extra capabilities.
One of the most important of these is that they can serve as carrier borne mid-air refuelling aircraft which would serve to extend strike ranges for F-35s if we were to use them on our carriers.
They can also serve as Anti-Submarine Warfare or Airborne Early Warning platforms but then this is a role currently covered by the Merlin fleet.
This means that the Osprey while excelling in many areas and out-performing current vehicles, does offer the UK and other nations substantial improvements. But this all comes at an extra cost and an expensive one at that.
Where 24 V-22 Ospreys could be bought the UK could buy 48 Merlin HM.2s and 35 Lynx Wildcat helicopters which not only fulfil the same capabilities (except mid-air refuelling) but give a greater fleet size which in turn gives much more force flexibility.
