A US Navy ban on T-45 flights has been lifted, although lower altitude restrictions have been put in place
. The trainers were barred from flying late last month after instructor pilots reported incidents of physiological problems by pilots while in the cockpit. The pilot trainer will now fly below 10,000 feet to avoid the use of the aircraft's On Board Oxygen Generator System as authorities continue to investigate the causes of physiological episodes experienced in the cockpit by aircrew. Air crew will also wear a modified mask that circumvents the OBOGS system.
Do you feel lucky…?
The T-45 Training System includes T-45 Goshawk aircraft, advanced flight simulators, computer-assisted instructional programs, a computerized training integration system, and a contractor logistics support package. The integration of all 5 elements is designed to produce a superior pilot in less time and at lower cost than previous training systems.
The US Navy uses the Hawk-based T-45TS system to train its pilots for the transition from T-6A Texan II/ JPATS aircraft to modern jet fighters – and carrier landings. This is not a risk-free assignment, by any means. Nevertheless, it is a critical link in the naval aviation chain. This DID FOCUS article covers the T-45TS, and associated contracts to buy and maintain these systems, from 2006 to the end of FY 2014.

Bell Helicopters is scheduled to deliver
the first three of 12 AH-1Zs
to Pakistan this summer, with the remainder to be delivered next year after being handed over to the US government. Approval for the deal was granted by Washington last April. The sale comes as the company expects the signing of a second export order for the H-1 series UH-1Y Venom utility and AH-1Z Viper attack helicopters in the coming months.
UH-1Y and AH-1Z
by Neville Dawson
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.

Latest updates[?]: February 17/17: Lockheed Martin has been contracted by the DoD external link for Trident II ballistic fleet missile production and deployed system support. The $540 million contract modification supports production efforts for the US.Navy and the British Royal Navy, who deploy the missile on their Ohio-class and Vanguard-class submarines respectively. Lockheed Martin received roughly $453 million in weapon procurement funds from the Navy, plus an additional $50.7 million from the Royal Navy. The company also received $36 million in fiscal 2017 operation and maintenance funds, which are set to expire at the end of the current fiscal year.
Trident II D5 Test Launch
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.

Further orders for Oshkosh's Joint Light Tactical Vehicles (JLTV) have been made by the US Army. 409 of the vehicles will be produced in a $179 million contract
, with work expected to be completed by this December. Initial low-rate production of the JLTV began last year, as the US Army and USMC look to replace their Humvees.
Ultra APV demonstrator
In an age of non-linear warfare, where front lines are nebulous at best and non-existent at worst, one of the biggest casualties is… the concept of unprotected rear echelon vehicles, designed with the idea that they’d never see serious combat. That imperative is being driven home on 2 fronts. One front is operational. The other front is buying trends.
These trends, and their design imperatives, found their way into the USA’s Joint Light Tactical Vehicle (JLTV) program, which aims to replace many of the US military’s 120,000 or so Humvees. The US military’s goal is a 7-10 ton vehicle that’s lighter than its MRAPs and easier to transport aboard ship, while offering substantially better protection ad durability than existing up-armored Humvees. They’d also like a vehicle that can address front-line issues like power generation, in order to recharge all of the batteries troops require for electronic gadgets like night sights, GPS devices, etc.
DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. JLTV certainly qualifies, and recent budget planning endorsements have solidifed a future that was looking shaky. Now, can the Army’s program deliver?

Advanced Hawkeye equipped with aerial refueling has made its debut flight
. Work carried out by Northrop Grumman included the installation of a probe along with associative piping and electrical cabling, as well as long endurance seats that will enhance the field of view in the cockpit and reduce fatigue over longer missions. A 2013 engineering, manufacturing, and development (EMD) contract has tasked the company with modifying three aircraft for testing followed by retrofits and production cut-in starting from 2018.
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.
