Boeing will provide
seven deployable crew trainers for P-8A Poseidon
maritime patrol aircraft to the US Navy. Delivers of the Deployable Mission Readiness Trainers (DMRTs) will commence in 2019 and includes its Weapons Tactics Trainer system, incorporating sonobuoy and ocean acoustics modeling. The trainers will allow Navy crews to continue simulator training while deployed abroad. The system will also be delivered to the Royal Australian Air Force.
Maritime surveillance and patrol is becoming more and more important, but the USA’s P-3 Orion turboprop fleet is falling apart. The P-7 Long Range Air ASW (Anti-Submarine Warfare) Capable Aircraft program to create an improved P-3 began in 1988, but cost overruns, slow progress, and interest in opening the competition to commercial designs led to the P-7’s cancellation for default in 1990. The successor MMA program was begun in March 2000, and Boeing beat Lockheed’s “Orion 21” with a P-8 design based on their ubiquitous 737 passenger jet. US Navy squadrons finally began taking P-8A Poseidon deliveries in 2012, but the long delays haven’t done their existing P-3 fleet any favors.
Filling the P-3 Orion’s shoes is no easy task. What missions will the new P-8A Poseidon face? What do we know about the platform, the project team, and ongoing developments? Will the P-3’s wide global adoption give its successor a comparable level of export opportunities? Australia and India have already signed on, but has the larger market shifted in the interim?

The US Navy has received delivery
of the air carrier USS Gerald R. Ford
from Huntington Ingalls Industries after completing acceptance trials on May 26. It is the first aircraft carrier to join the fleet since USS George H. W. Bush in 2009, and features a larger flight deck, the ability to host more aircraft, additional weapons and aviation fuel storage, and the Electromagnetic Aircraft Launch System and Advanced Arresting Gear, giving the Navy increased sortie rates by one-third when compared to Nimitz-class vessels. The Ford will be commissioned later this summer and will be declared operational in 2020.
USA’s Nimitz Class &
UK’s Invincible Class
Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.
Nimitz Class cutaway
As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.
DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

A new start project
listed for Fiscal Year 2017 will see the US Army look for rotor-craft designs to fund the next-generation of Future Vertical Lift (FVL
) helicopters. If approved by Congress, FVL could initially produce mid-weight replacements for the long-serving Sikorsky UH-60 Black Hawk and Boeing AH-64 Apache types. The news comes as both Boeing-Sikorsky and Bell Helicopters are developing their own next-gen FVL contributions which aim to have their first flights by the end of 2017. The Boeing-Sikorsky offering, the SB-1 Defiant
compound coaxial helicopter has been developed as a precursor FLV under the Army’s Joint MultiRole (JMR) technology demonstration, while Bell is offering its V-280 Valor tiltrotor
The future is now
The JMR-TD program is the science and technology precursor to the Department of Defense’s estimated $100 billion Future Vertical Lift program, which is expected to replace between 2,000-4,000 medium class UH-60 utility and AH-64 attack helicopters after 2030.
In reality, FVL will fall far short of that number if it ever goes ahead, but those figures are the current official fantasy. While they’re at it, the Pentagon wants breakthrough performance that includes the same hovering capability as smaller armed scout helicopters, and a 100+ knot improvement in cruising speed to 230+ knots. That’s almost certainly achievable, thanks to new developments that involve very different helicopter designs.
