US Air Force fleets evolution

In these days in which the sequester is being often in the media, this will be a very brief post to bring to the memory a study prepared by Mitchell Institute for Airpower Studies, founded by the Air Force Association, “ARSENAL OF AIRPOWER: USAF Aircraft Inventory 1950-2009” [PDF, 6.5 MB], published in November 2010.

I wanted to bring forward some comments and two graphics:

  • “To put matters into perspective, a single C-17 can carry the equivalent of 15 C-47 loads (as well as cargo that could never fit inside a C-47) and deliver that cargo anywhere in the world within hours without requiring en-route staging bases.”
  • “The average cost of a flying hour over the past decade is around $23,000 (in constant FY11 dollars), compared to about $11,000 in 1985 and roughly $4,800 in 1970.”
  • “For example, a single B-2 now armed with 80 Joint Direct Attack Munitions (JDAMs) could strike as many targets as five of the 75-aircraft 1991 Gulf War era packages.”

KC-46 EMD contract 101

The US Government Accountability Office (GAO) has recently published a report about the KC-46 Tanker Aircraft [PDF, 1.2 MB]. In it the GAO reviews the situation of the program, measures introduced, costs, technology development, etc. In the first page it summarizes:

“The KC-46 program 2012 estimates for cost, schedule, and performance are virtually the same as last year’s, with the contractor running very close to the planned budget and schedule”.

On the technical side it points to several challenges: flight test plan, completion of engineering drawings, relocation of personnel and facilities related to defense equipment, etc.

However, in this post I wanted to focus only on the costs and contractual sides of the program, given the amount of articles that we could read about it during the past year. Several news have reported about the cost overruns in the program and about how these were to be born by Boeing.

The last time I read about the topic, the reported overrun was of about 1.2bn$ on a 4.4bn$ contract, out of which ~500M$ would be born by USAF and the remaining 700 M$ by Boeing (see articles from Bloomberg, Aviation Week, The Seattle Times…).

But, where do these figures come from?

One of the many things I like of the USA is the transparency in making lots of information and data available to the public, for example, budgeting information of the Air Force, GAO’s assessments, hearings at the Senate and House of Representatives Committees, etc. Thus, you can find:

Contractual framework

From the USAF budgeting material, page 675, under the paragraph “E. Acquisition Strategy“, the explanation of the different contracts structure for the KC-X program (the name of the program prior to the contract award) can be found:

“The KC-46 program released a final Request for Proposal (RFP) on 24 Feb 2010, and entered source selection on 9 Jul 2010. The KC-46 program held a Milestone B Defense Acquisition Board (DAB) on 23 Feb 2011, received approval to enter EMD from OSD AT&L on 24 Feb 2011, and awarded the KC-46 contract to Boeing on 24 Feb 2011 to develop and procure 179 KC-46 aircraft. The KC-46 contract procurement was conducted via a full and open competition per Federal Acquisition Regulation (FAR) Part 15, and resulted in a FY 2011 EMD Fixed Price Incentive Firm (FPIF) contract. The EMD phase will develop, build, and test four KC-46 aircraft, and will qualify receiver aircraft.

Production will begin in FY 2015 with two Low-Rate Initial Production (LRIP) lots (Firm Fixed Priced (FFP)) and then Full-Rate Production (FRP) options (FFP with Not to Exceed (NTE) + Economic Price Adjustment (EPA)). The LRIP and FRP options will be exercised following successful completion of Operational Assessments (OAs) for the LRIP decisions, and a successful completion of Initial Operational Test and Evaluation (IOT&E) for the FRP decision.”

Thus, so far only the Engineering Manufacturing and Development (EMD) contract  phase has been contracted, on February 24th Feb 2011 (you can see Boeing and DoD press releases).

Cost Assessment by GAO:

From the Government Accountability Office (GAO) assessment of the program, referred above:

“The current development cost estimate of $7.2 billion as reported in October 2012 includes $4.9 billion for the aircraft development contract and 4 test aircraft, $0.3 billion for the aircrew and maintenance training systems, and $2 billion for other government costs to include program office support, government test and evaluation support, contract performance risk, and other development risks associated with the aircraft and training systems. [...]

Through December 2012, Boeing has accomplished approximately $1.4 billion (28 percent) in development work and has more than $3.5 billion (72 percent) in estimated work to go over the next 5 years. [...]

Barring any changes to KC-46 requirements by the Air Force, the contract specifies a target price of $4.4 billion and a ceiling price of $4.9 billion at which point Boeing must assume responsibility for all additional costs. [...]“

See the table below showing Air Force and Boeing contract amounts and estimates:

KC-46 EMD Contract & Estimates.

KC-46 EMD Contract & Estimates (Source: GAO).

The report from GAO offers the following graphic referring to what they call “management reserves“:

KC-46 EMD Management Reserves (Source: GAO)

This graphic shows well the rate at which Boeing has been supposedly burning its margins. However, it does not reflect at all the nature of the issue, related to the type of contract this “Engineering Manufacturing and Development” (EMD) contract: a Fixed Price plus Incentive Firm type of contract (FPIF).

Fixed Price Incentive Firm contracts

It is not easy to find good literature online about these types of contracts. The Wikipedia for instance does not have yet an article on FPIF contracts, but only on the calculation of the Point of Total Assumption. However, you can find a couple of good sites with explanations and examples of FPIF contracts here and here [PDF from the US Army].

Some concepts that we need to bear in mind are (definitions from the link above):

Target Cost (TC): The initially negotiated figure for estimated contract costs and the point at which profit pivots.
Target Profit (TP): The initially negotiated profit at the target cos
Target Price: Target cost-plus the target profit.
Ceiling Price (CP): Stated as a percent of the target cost, this is the maximum price the government expects to pay. Once this amount is reached, the contractor pays all remaining costs for the original work.
Share Ratio (SR): The government/contractor sharing ratio for cost savings or cost overruns that will increase or decrease the actual profit. The government percentage is listed first and the terms used are “government share” and “contractor share.” For example, on an 80/20 share ratio, the government’s share is 80 percent and the contractor’s share is 20 percent.
Point of Total Assumption (PTA): The point where cost increases that exceed the target cost are no longer shared by the government according to the share ratio. At this point, the contractor’s profit is reduced one dollar for every additional dollar of cost. The PTA is calculated with the following formula. [thus, PTA = (Ceiling Price - Target Price)/Government Share + Target Cost]

Where can we get these figures for the KC-46 EMD contract? Some of them are referred to in the different reports and budgeting materials (explicitly or implicitly) and others can be found in the following letter from US Senator John McCain to the DoD from July, 15 2011 [PDF, 400 KB].

Thus for the KC-46 EMD contract we have:

  • Target Cost: 3.9 bn$.
  • Target Profit: 500 M$.
  • Target Price: 4.4 bn$
  • Ceiling Price: 4.9 bn$
  • Share Ratio: 60% / 40% (Government / Boeing).
  • Point of Total Assumption (calculated): ~4.73 bn$.

With this information we can produce the typical FPIF contract curve, which is the only thing which is missing in ALL the news, budgeting materials, GAO reports, etc., that I have read and is the most illustrative graphic to understand what is going to happen if the cost overruns keep piling and who is going to bear which amount of the cost from which point:

Quiz: How loaded do US Air Force transport aircraft operate?

Let me share with you one funny quiz I did for some colleagues at the office:

On average, how loaded do US Air Force transport aircraft, C-130 Hercules and C-17 Globemaster, operate? (as a percentage of their maximum payload capacity: let’s take the figures reported by the US Air Force, ~16.5 tonnes for the C-130 -”maximum normal payload”-and 77.5 tonnes for the C-17)

Before continuing reading below, take your chance in the poll below, where I offer 4 possible responses: 3 from my colleagues’ responses to the quiz plus the correct one:

Background. Before posing the quiz to my colleagues we were commenting on a piece of news of an Antonov 124 which had landed in Spain to load some equipment weighing 1,000 kg. The An-124 reported payload capacity is 150 metric tonnes. For those not being number-crunchers: that means using the one of the biggest cargo aircraft to load it up to 0.7% of its capacity.

After having read this last paragraph you may have changed your opinion as to which is the correct answer to the quiz.

I based the correct result on a news release from the US Air Force dating from the beginning of 2007. At that time I was working in Airbus Military strategy where I would like to pick up any number related to aircraft and play with it (the hobby has stayed). That release offered figures US Central Command air transport operations, including operations Enduring Freedom (Afghanistan) and Iraqi Freedom. Find the results from that short number play:

US Air Force average loads (in tonnes) for C-130 and C-17 during 2005 and 2006.

US Air Force average loads (in tonnes) for C-130 and C-17 during 2005 and 2006.

If you do the math, you will immediately get the right answer: C-130 Hercules, 22% and C-17 Globemaster, 17%.

“What a waste of resources!” you may think. A former senior colleague pointed to that result: “You buy a Mercedes to travel with the family and baggage, then on a Sunday when having to go out to get some bread or any week day when you go alone to work… when you get to the garage and find a Mercedes… Guess which car you take?”

Wrong forecasts

Close to midnight of past Thursday we learnt that the winner of the KC-X competition to provide the aerial refuelling aircraft to the US Air Force was Boeing. That was cold news for our company.

I had just tweeted the previous day my bet on the competition:

I never get it right...

To reach to that conclusion I had done some numbers for fun on a late Friday afternoon some months ago in a similar fashion than the defence analyst Scott Hamilton showed in his blog. It is clear that I got it completely wrong.

As I have often told to my friends and colleagues, I am extremely bad with these predictions, as I was already mistaken when the JCA and the previous KC-X competitions were decided…

A note of humour: as my brother points out in fact I am very reliable, you just have to bet to the opposite option of my forecast.

Another colleague told us yesterday “you look like economists explaining your miscalculations…”, as someone put it “it is already hard to explain the past, it is even more difficult to predict the future”.

Already looking forward to the next win.

After the year 2015, there will be no airplane crashes

When I was writing in the previous post about Alberto Dubois idea of evolution being exponential I had in mind the book “Augustine’s Laws”, to which I have referred many times in this blog.

Today, I read a very good article in last week’s issue of The Economist, “Defence spending in a time of austerity”, which describes the current situation of defence budgets around the World and how it will affect many programmes…

The article itself is referring to the computing evolution depicted by Dubois and some other exponential trends identified by Augustine, such as the increased use of computer power and software.

I especially liked the update of Augustine’s chart for the Law XVI which says:

“In the year 2054, the entire defence budget will purchase just one aircraft. This aircraft will have to be shared by the Air Force and Navy 3½ days each per week except for leap year, when it will be made available to the Marines for the extra day.”

Augustine's Law XVI chart, updated by The Economist.

Thus, in the last 25 years, since Augustine wrote his book, the business has not improved much. This situation provokes that different countries have to share weapons, e.g., C-17 transport aircraft (Strategic Aircraft Capability, operated for several countries from Hungary), SALIS (“Strategic Airlift Interim Solution”, chartering of ex-soviet An-124 to NATO countries)…

One of the most striking situations that may come to happen is that UK and France share two aircraft carriers. Carriers were considered essential to have control over oceans… however, if France is going to scale its fleet down to one single carrier: what would happen during the long months when it will be in overhaul?

Lately there have been much discussion about this sharing scheme, though it is still denied by officials. Consider that just back in 1940, the British Royal Navy destroyed much of the French fleet in the Operation Catapult.

Other interesting point is the trend towards using unmanned aircraft versus piloted ones. Already in the “Aircraft Investment Plan Fiscal Years (FY) 2011-2040” (PDF, 0.2MB) that the US Air Force submitted together with its FY11 budget request, it forecasted that the number of unmanned aircraft will almost triple in the next ten years, while the rest of fleets would be either just renewed or decreased.

Nevertheless, this may never come to happen if we take Augustine’s Law Number XIV:

“After the year 2015, there will be no airplane crashes. There will be no takeoffs either, because electronics will occupy 100 percent of every airplane’s weight”.
