Jan. 31, 2022, © Leeham News: A third company will offer a tanker to the US Air Force when the KC-Y Request for Proposal is issued this year.
Kansas Modification Center (KMC) and the National Institute for Aviation Research (NIAR) will propose converting used Boeing 777-300ERs to tankers. Jim Gibbs, president and CEO of KMC, already submitted information to the Air Force in response to last year’s Request for Information.

Gibbs, in an interview with LNA, said that the concept is to offer the Air Force a tanker not for front-line combat zones, but along the lines of the conversions used by Omega Air. Omega provides non-combat air refueling service for the US Navy, Air Force, and some NATO countries. It operates after-market conversions of the Boeing 707 and McDonnell Douglas DC-10. IAI Bedek also undertook after-market tanker conversions of the 707 and Boeing 767. The UK’s Royal Air Force converted Vickers VC-10s and Lockheed L-1011s to tankers.
Choosing the 777-300ER
Gibbs said the KMC and NIAR chose the 777-300ER over the 777-200ER or LR as the better platform, in their view.
“The 777, especially the -300, makes an enormous amount of sense right now. It’s a modern aircraft, very low time, the aircraft itself can haul about 200,000 pounds on a structural payload with very minor modifications to it,” Gibbs said. “You can take that aircraft, add some existing capabilities on it, such as the existing boom of KC-135, and simplify the fuel offload process. I think you would have a very capable tanker. If you have a mission radius of 3,000 miles, a 777 can still offload 150,000 pounds of fuel.
“The -300ER has a higher gross weight than anything, with the exception of the -200LR. If you look at the available aircraft for conversion and the available feedstock on it, the LR and the type of aircraft available for that are very minimal compared to the -300ER feedstock. The -300 is a bigger aircraft, it shares the same wing box and a lot of structure with the -200, or most of the structure, besides the plugs. We need to inject 100 tankers into the fleet. There’s not that many -200LRs out there,” Gibbs said.

Introduction
Jan. 31, 2022, © Leeham News: ATR is now effectively the only turboprop manufacturer outside of China and Russia in the 40-80 seat sector. The models are the ATR 42-600, ATR 42-600S (STOL), and ATR 72-600.
The series was built on simplicity with unpowered controls and the simplest possible systems. It has worked well for ATR when selling to markets that want airlift to the lowest possible cost. It also means the design is at its limits capacity and speed-wise, any more capacity or performance and it needs powered controls and more elaborate systems. It was behind ATR’s desire to develop a new, larger model in the past.
But ATR has little reason to develop a new turboprop now that it is in a monopoly position. This could change if Embraer proceeds with its concept for a new family of two turboprops, a 70- and a 90-seat aircraft. Embraer’s base design could form the basis of a hydrogen-burning gas turbine model in the future.

Part 3 of the Boeing focus for the USAF Aerial Refueling Tanker
Jan. 31, 2022, © Leeham News: Following the 9/11 terrorist attacks in the United States, Boeing offered the US Air Force a lease deal for 100 aerial refueling tankers based on the 767-200.

The concept of leasing tankers had been floated before. Boeing at one point proposed creating a 747-based tanker and leasing it to the Air Force. The idea went nowhere, but this one gained traction.
The leasing concept formed just before Jim Albaugh arrived at IDS, but he was president as it progressed and through the subsequent competition, called KC-X, against Northrop Grumman-EADS (Airbus) after the lease deal was canceled.
“You go back in history, and it started out with the need for the Air force to replace the 707s which were their tanker fleet for a long time, and they were getting old,” recalls Albaugh, the CEO of Boeing’s Integrated Defense Systems unit at the time. IDS is now called Boeing Defense, Space and Security (BDS).
Lockheed Martin sees LMXT as complementary to KC-46A, not competitive

Jan. 30, 2022, © Leeham News: Lockheed Martin’s LMXT US Air Force refueling tanker will be a complementary offer to the service in the forthcoming KC-Y competition.
Larry Gallogly
In an exclusive interview with LNA earlier this month, Lockheed Martin (LMCO)’s LMXT Campaign Director, Larry Gallogly, said the Air Force wants an airplane that is bigger, has more range, and more fuel offload than the incumbent Boeing KC-46A. This fits the LMXT, based on the Airbus A330-200 Multi-Role Tanker Transport (MRTT) now in production.
Airbus partnered with LMCO in 2018 to prepare for the KC-Y competition. Airbus has 61 orders for the MRTT from around the world. Boeing is building 179 tankers for the Air Force from the original KC-X competition. It has a handful of orders from other countries.
The KC-Y contact will be for up to 160 tankers. The competition will pit Boeing and Airbus against each other for the third time. Airbus first teamed with Northrop Grumman in the first round of the KC-X campaign. Northrop won the contract, but the award was protested successfully by Boeing. Northrop dropped out of the recompete, with Airbus going alone. This time, Lockheed Martin will be the lead, and Airbus the subcontractor.
The two fights were bitterly waged in the public and political domains. LMCO hopes to avoid a repeat.
No plans to relitigate
“We have, from the start of this, with both ourselves and Airbus, have had no intention of re-litigating the [KC-X] competition,” Gallogly said. “Our goal has always been to provide what we consider to be a complementary capability. There are going to be 179 KC-46s out there, but there are significant capability gaps that the US Air Force has that this LMXT can fill. We are not trying to provide the same capability in a different wrapper. Our goal is to provide a very different capability and, again, fill those gaps.”
Gallogly said that after talking to the Air Force and Pentagon repeatedly, from the Air Mobility Command to transportation command to the individual theater commanders, to the people in the Pentagon, “what we heard consistently was that the gap exists for fuel offload at strategic ranges. You know as everybody who focuses on the Pacific Theater, you’re faced with the tyranny of distance there, and we needed to provide as much fuel offload as we possibly could.”
Bjorn’s Corner: Sustainable Air Transport. Part 4. Reality checks.
By Bjorn Fehrm
January 28, 2022, ©. Leeham News: Having discussed where investments would be the most efficient in alleviating our Greenhouse gas problems and identified the low-hanging fruit, we now look at new technology airplanes that can improve the situation.
We start with classical airliners, working our way from small types to the largest, then we discuss the impact of new transport forms like VTOLs for short-haul transportation.
As we will use the Leeham Aircraft Performance Model in some of the work, there will be extra articles (for this one, a Part 4P) which are Paywall, where we use the model to generate deeper data and understanding.

Jan. 27, 2022, © Leeham News: Despite vociferously criticizing Boeing over delays, technical difficulties and uncertainties over certification, delivery dates and performance, the president of Emirates Airline said the carrier is committed to the 777X.
Tim Clark said industry talk that Emirates may swap orders for the 777X for additional Boeing 787s isn’t correct.
Clark made his remarks in an interview with LNA on January 11. He also said he plans to retire within the next six months. Clark previously announced a retirement date but agreed to stay on to see Emirates through the pandemic crisis.
Summary
- “Boeing made life difficult.”
- Three-year delay has repercussions.
- The future of 777-8 passenger model is uncertain.
Carbon footprint: Regional jet versus turboprop, how large is the difference?

Introduction
January 27, 2022, © Leeham News: Last week, we kicked off a series of articles where we will measure what difference our choice of flying makes to the primary Greenhouse gas emission, CO2.
We have upgraded our airliner performance model for the series to give a direct output of the CO2 emissions for the flights in different phases.
We start this week by comparing a typical domestic feeder flight of 300 nm, with an example route of Cleveland to Chicago O’Hare. What will be the time differences? And the fuel burn and CO2 emission difference?
To make it a fair comparison, we’ll use present generation aircraft flying on the US market, the Embraer E175 and De Havilland’s DH 8-400. We will fly the DH 8 at a high-speed cruise to keep the flight time differences within 10 minutes.

Summary
- As expected, the turboprop is the more efficient mode of transportation on the route. It consequently emits less CO2 per transported passenger.
- With new, more comfortable turboprops in the works, the drive for sustainability could see a return of the turboprop to the US market.
Boeing has cash flow positive 4th quarter, 1st since 2019; takes charge on 787 program
Jan. 26, 2022, © Leeham News: Boeing reported its first cash flow positive quarter, the fourth quarter, since early 2019 today as it issued its 2021 financial results. The 737 MAX was grounded worldwide March 10-13, 2019. The company was cash flow positive by $700m.
For the full year, Boeing remained cash flow negative, at $3.4bn. Boeing recorded a $3.4bn non-cash, pre-tax charge of $3.5bn on the 787 program. Deliveries have been stalled since October 2020.
“Don’t delude the public” on environmental advances in aviation

In a fanfare series of panels and announcements, IATA set a goal of industrial carbon neutrality by 2050. But in reality, this was a step backwards from a goal described in 2011 by Jim Albaugh, then-president of Boeing Commercial Airplanes. Albaugh made his remarks in a speech before the Royal Aeronautical Society.
At the IATA AGM, Tim Clark, president of Emirates Airline, cautioned the industry: “Don’t make promises you can’t keep.”
LNA spoke with Clark this month, who expanded on his IATA appearance.
