USAF New Bomber – B-21 – Gets a Base

The good news? 2006 saw a convergence of opinion within the USAF that a new long-range strike platform was needed. This is understandable given the B-52H Stratofortress fleet’s age (40-50 years), the B-1B Lancer’s internal power and electronics issues, both of these platforms’ low survivability against advanced air defense systems, and the B-2A Spirit stealth bomber’s very small numbers (21, of which 7-12 are generally operational). The unmanned J-UCAS program, meanwhile was seen as having inadequate range and payload (Boeing X-45C: 1,400 mile radius with 8 GBU-39 Small Diameter Bombs). The USAF decided that J-UCAS wasn’t a solution and pulled out, stalling American UCAV development until the Navy chose to go ahead with the carrier-based N-UCAS.

The bad news? They seemed to have little idea of exactly what they wanted in their bomber. The FY 2010 budget killed those plans anyway, but in September 2010, pressure to field a new bomber began to rise again. By the time fiscal year 2015 budget planning was in motion, both DoD and the Air Force seemed committed to making the program one of the service’s top 3 priorities.

E-2D Hawkeye: The Navy’s New AWACS

Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.

The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

KC-46A Pegasus Aerial Tanker Completes Firsts

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

Trident II D5 Missile: Keeping Up with Changing Times

Nuclear tipped missiles were first deployed on board US submarines at the height of the Cold War in the 1960s, to deter a Soviet first strike. The deterrence theorists argued that, unlike their land-based cousins, submarine-based nuclear weapons couldn’t be taken out by a surprise first strike, because the submarines were nearly impossible to locate and target. Which meant that Soviet leaders could not hope to destroy all of America’s nuclear weapons before they could be launched against Soviet territory. SLBM/FBM (Submarine Launched Ballistic Missile/ Fleet Ballistic Missile) offered shorter ranges and less accuracy than their land-based ICBM (Inter-Continental Ballistic Missile) counterparts, but the advent of Trident C4 missiles began extending those ranges, and offering other improvements. The C4s were succeeded by larger Trident II D5 missiles, which added precision accuracy and more payload.

The year that the Trident II D5 ballistic missile was first deployed, 1990, saw the beginning of the end of the missile’s primary mission. Even as the Soviet Union began to implode, the D5’s performance improvements were making the Trident submarine force the new backbone of the USA’s nuclear deterrent – and of Britain’s as well. To ensure that this capability was maintained at peak readiness and safety, the US Navy undertook a program in 2002 to replace aging components of the Trident II D5 missile called the D5 Life Extension (LE) Program. This article covers D5 LE, as well as support and production contracts associated with the American and British Trident missile fleets.

F-35 Lightning: The Joint Strike Fighter Program

The $382 billion F-35 Joint Strike fighter program may well be the largest single global defense program in history. This major multinational program is intended to produce an “affordably stealthy” multi-role fighter that will have 3 variants: the F-35A conventional version for the US Air Force et. al.; the F-35B Short Take-Off, Vertical Landing for the US Marines, British Royal Navy, et. al.; and the F-35C conventional carrier-launched version for the US Navy. The aircraft is named after Lockheed’s famous WW2 P-38 Lightning, and the Mach 2, stacked-engine English Electric (now BAE) Lightning jet. Lightning II system development partners included The USA & Britain (Tier 1), Italy and the Netherlands (Tier 2), and Australia, Canada, Denmark, Norway and Turkey (Tier 3), with Singapore and Israel as “Security Cooperation Partners,” and Japan as the 1st export customer.

The big question for Lockheed Martin is whether, and when, many of these partner countries will begin placing purchase orders. This updated article has expanded to feature more detail regarding the F-35 program, including contracts, sub-contracts, and notable events and reports during 2012-2013.

Virginia Block III: The Revised Bow

“GDEB Receives $148M as Virginia Class Lead Yard” described changes to the Virginia Class submarine’s design that are expected to reach 20% of the $200 million savings goal by the time orders for the versatile sea attack/ land attack/ special forces submarines rise to 2 per year, in 2012.

The bow changes cover the FY 2009-2013 ships, referred to as Block III. SSN 774 Virginia – SSN 777 North Carolina are Block I, and SSNs 778-783 will be Block II. Block III begins with the 11th ship of class, SSN 784. Long lead time component orders began May 22/08, and the submarine is expected to be ready for delivery around 2015. A fuller explanation of Block III’s extensive bow changes, and an accompanying graphic, may be found below – along with contract updates that include additional improvements and sonar development.

CH-53K: The U.S. Marines’ HLR Helicopter Program

The U.S. Marines have a problem. They rely on their CH-53E Super Stallion medium-heavy lift helicopters to move troops, vehicles, and supplies off of their ships. But the helicopters are wearing out. Fast. The pace demanded by the Global War on Terror is relentless, and usage rates are 3 times normal. Attrition is taking its toll. Over the past few years, CH-53s have been recalled from “boneyard” storage at Davis-Monthan AFB in Tucson, AZ, in order to maintain fleet numbers in the face of recent losses and forced retirements. Now, there are no flyable spares left.

Enter the Heavy Lift Replacement (HLR) program, now known as the CH-53K. It aims to offer notable performance improvements over the CH-53E, in a similar airframe. The question is whether its service entry delay to 2018-2019 will come too late to offset a serious decline in Marine aviation.

Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

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.

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.

APKWS II: Laser-Guided Hydra Rockets in Production At Last

The versatile Hydra 70mm rocket family is primed for a new lease on life, thanks to widespread programs aimed at converting these ubiquitous rockets into cheap laser-guided precision weapons. Conversion benefits include cost, use on both helicopters and fighters, more precision weapons per platform, low collateral damage, and the activation of large weapon stockpiles that couldn’t be used under strict rules of engagement.

Firms all over the world have grasped this opportunity, which explains why strong competition has emerged from all points of the compass. America’s “Advanced Precision-Kill Weapon System (APKWS)” is one of those efforts, but the road from obvious premise to working weapon has been slow. After numerous delays and false starts since its inception in 1996, an “APKWS-II” program finally entered System Design and Development (SDD) in 2006. In 2010, it entered low-rate production, and it was fielded to the front lines in 2012. That date will still put APKWS on the cutting edge of battlefield technology, as a leading player in a larger trend toward guided air-to-ground rockets.

Snakes and Rotors: The H-1 Helicopter Program

The US Marines’ helicopter force is aging at all levels, from banana-shaped CH-46 Sea Knight transports that are far older than their pilots, to the 1980s-era UH-1N Hueys and AH-1W Cobra attack helicopters that make up the Corps’ helicopter assault force. While the tilt-rotor V-22 Osprey program has staggered along for almost 2 decades under accidents, technical delays, and cost issues, replacement of the USMC’s backbone helicopter assets has languished. Given the high-demand scenarios inherent in the current war, other efforts are clearly required.

Enter the H-1 program, the USMC’s plan to remanufacture older helicopters into new and improved UH-1Y utility and AH-1Z attack helicopters. The new versions would discard the signature 2-bladed rotors for modern 4-bladed improvements, redo the aircraft’s electronics, and add improved engines and weapons to offer a new level of performance. It seemed simple, but hasn’t quite worked out that way. The H-1 program has encountered its share of delays and issues, but the program survived its review, and continued on into production and deployment.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers the H-1 helicopter programs’ rationales and changes, the upgrades involved in each model, program developments and annual budgets, the full timeline of contracts and key program developments, and related research sources.
