Introduction
Dec. 28, 2014: Two challenges to the duopoly of Airbus and Boeing in the 150-220 seat single-aisle sector move forward in development in 2015, but neither is in a position to be a threat for the balance of this decade, nor even in the next.
Both challenges, the COMAC C919 from China, and the Irkut MC-21 from Russia, will for various reasons fall short of the Airbus A320/321 and Boeing 737-8/9 and plans to design the next generation new single-aisle airplane.
Summary
The 10th Chinese airshow at Zhuhai opened today. It was a day with fewer announcements than expected from the usual suspects (Airbus, Boeing…) but the Chinese industry did not disappoint. China is now showing more and more of its coming might as a player on the aeronautics arena.
The most prominent displays at this show were on the military side, where China has two stealth aircraft projects flying (the large Chengdu canard J-20 and the smaller Shenyang J-31) while their canard Chengdu J-10 was flying the display circuits overhead (Figure 1).

All aircraft are of latest structural and aerodynamic design if not in engines and systems. This is a big difference to previous shows where the Russian Sukhoi and MIG aircraft and their local copies did the flying display until 2008. Since then everything has changed and now China and USA are the only countries in the world with two different stealth designs flying. USA has one in operation (F-22) and one close to (F-35) whereas China still has many years to go until they have their new aircraft operational. But it is significant that the old aeronautical behemoths Europe and Russia have none respective one (PAK-50) stealth fighter in flight test.

Part 3 of 3
Introduction
In Part 2 of our three-part 757 Replacement analysis, we took a close look at Airbus’ new 97 tonne take-off weight A321neo, revealed in a world exclusive by
Leeham News and Comment October 21. We analyzed the A321neoLR’s capabilities and limitations when compared to Boeing 757-200W and we saw that it could do the international flights that the 757-200 does with about 25% better efficiency. In this final Part 3, we will now compare the 757 and A321neoLR against what can be Boeing’s reaction, a clean sheet New Single Aisle, NSA, or New Light Twin Aisle, (NLT). First the conclusions from Part 2:
