South Korea may join the US Navy, India, and Australia in operating the P-8A
maritime patrol aircraft, according to defense ministry officials. If given the go ahead, Seoul may purchase four of the aircraft
to help expand their surveillance and anti-submarine warfare capabilities following submarine launched ballistic missile (SLBM) tests by North Korea. The aircraft can fly at altitudes up to 41,000 feet and are capable of striking enemy submarines immediately upon detecting them with weapons such as the MK 54 torpedo.
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?

Huntington Ingalls has been awarded
a $152 million US Navy contact for advance planning for the construction of the aircraft carrier Enterprise (CVN 80). The third aircraft carrier in the Gerald R. Ford class was named in honor of the Navy’s first nuclear-powered aircraft carrier, USS Enterprise (CVN 65). Work to be carried out
includes engineering, design, planning, and procurement of long-lead-time material, and will be performed at the company’s Newport News Shipbuilding division through March 2018. Construction is to commence in 2018 and be delivered to the Navy in 2027.
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.
