Bell Helicopters is considering a plan
to manufacture AH-1Z Viper
attack helicopters in Romania within the next 4-5 years. News of the deal comes almost twenty years after a previous attempt to assemble the AH-1 in the country fell through. The announcement follows Bells' signing
of a memorandum of understanding (MoU) with Romanian company IAR-Ghimbav Brasov Group last November that would see the local firm cover possible maintenance, repair, and overhaul (MRO) of the AH-1Z should it be procured by Bucharest. While Romania has yet to launch a formal tender for their replacement, Bell is just one of several manufacturers, including Airbus, who are positioning themselves for an anticipated requirement.
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.

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.

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.
