Strategic Airlift Capability  –  Procurement  –  February 2006

Strategic Airlifters: a Comprehensive Comparison between the Boeing C-17 and the Antonov An-124-100   [Part 1]

Herman A. Kurapov,  Candidate,  Master of Engineering in Logistics, MIT  [1]


[Ed:  Canada lacks a genuine strategic airlift capability. Although referred to as a strategic airlifter, the in-service CC-150 Polaris is simply a civilian Airbus jetliner.

The CF’s  Future Strategic Airlift project  dominated  much of  Air Force planning from early 2000 until it was cancelled by the Minister of National Defence in April 2003.  Although the FSA examined both the  Lockheed Martin C-130J and  Airbus A400M,  neither of these two tactical transports could be seriously considered as a  strategic airlifter.  Also  under  consideration  was  the  Ukraine’s  experimental Antonov An-70  (or  its  proposed  ‘westernized’ derivative,  the unbuilt  An-7X ).

Dominating FSA considerations was the American  Boeing C-17 Globemaster III. In the background, was the de facto choice of CF strategic airlift  –  the enormous Antonov An-124 Ruslan leased to do the job from Antonov or from Volga Dnepr.

The author has firsthand experience working  with  Volga Dnepr  and the  An-124. In this article,  he will review and compare the capabilities  of  both  the  C-17  and the  An-124-100,  while  laying  out  various  options  for  the  Canadian  Forces.]

Introduction

Strategic airlift is a matter of great importance for the Canadian Forces (CF) but airlift is also critical for the Canadian national economy in general.  The choice of  strategic airlifter type for the CF can have huge implications not only for the Canadian military but for the Canadian civilian air transport industry as well.

Canada also lacks a civilian airlift capability. There are no long-range, heavy air freighters in Canada, and this seriously undermines the competitiveness of the Canadian economy. This, along with the high purchase cost of strategic airlifters, is why all Canadian taxpayers should be concerned.

With the revived interest in a Canadian Forces strategic airlift capability, the Government of Canada must make two separate choices:

   1)  the type of aircraft that best suits CF strategic lift needs
   2)  the ‘model’ for the acquisition of a strategic airlifter  –  whether to purchase,
        to lease, or  to arrange some combination of the two.

I will analyze the pros and cons of different aircraft types for the strategic airlift requirement, the comparative advantages of the various acquisition models, and possible strategies for future ‘profit-generating’ operations of this airlifter.

Aircraft Types

The Airbus A400M has not yet been built and  the Antonov An-7X appears to have been cancelled. So, this analysis will be limited to the two production types that actually exist today:  the Boeing C-17 and the Antonov An-124-100 Ruslan.

Canadian Forces pilots have expressed their preference for the C-17. The C-17 is aviation’s equivalent of the Lamborghini  –  very sophisticated and fun to drive. Certainly more fun than the An-124-100,  which is more  ‘truck’ than  ‘sportscar’.

But, this isn’t about fun. When going out for a weekly shopping trip, do we really need a ‘very cool’ piece of equipment to drive? Or is it more important to have the greatest practical carrying capacity? What about when the price comes into play? The cost of purchase and of yearly operations? There are many important consid- erations to take into account besides whether the aircraft in question ‘looks cool’.

Below  is  a  short  comparative analysis  of   the  C-17  and  the An-124-100, comprised of  three major  characteristics:  technical aspects, financial considerations and  the  long - term, operational costs of  both aircraft types.

Technical Aspects

For a strategic airlifter, the technical characteristics deemed most important are: payload,  cargo-cabin volume / max volume,  and  range with maximum payload.

Critical to the effectiveness of a modern strategic airlifter is its capability to carry heavy, out-sized cargo  –  projecting and sustaining an effective combat force as close as possible to potential battle, or humanitarian/peacekeeping mission areas.

Threats to Canadian interests have changed in recent years. The size and weight of  Canadian Forces mechanized firepower and equipment have grown such that, currently, 75% of air shipments for the military qualify as heavy, out - sized cargo.

So the main questions are these:  How far can the aircraft fly with a  normal  load? How heavy can the  maximum  load  be?  How  big a  load can fit  into the aircraft?

Let’s compare the An-124-100  and C-17 based on these technical characteristics.

Aircraft
Type
Maximum
Load
Maximum
Volume
Range
Max Load
Range with
a 77t Load
An-124-100 120 t 1270 m3 3333 km 5925 km
Boeing C-17 77 t 592 m3 4444 km 4444 km

From  this  table  we can see  that,  compared  with the C-17,  an An-124-100  has:

   •    55 % greater maximum load than the C-17
   •  115 % more of a maximum cargo-cabin volume
   •    33 % greater range (when carrying 77t  –  the C-17’s maximum load)

Put simply, the An-124 can carry loads which are 1.5 times heavier, cargo that is more than twice as large, and it can travel almost 1,500 km further than the C-17 with a similar load.

Taking an average of the above performance characteristics (55%, 115% & 33% better / 3), we come to the conclusion that An-124-100 has a critical strategic airlifter performance which is 68% better than that of the C-17.
