Bell Helicopters is keen to sell its AH-1Z
attack helicopter as a solution to Japan's AH-X program
. As part of preparations the company has teamed with engineers from Fuji Heavy Industries on modification work to the helicopter aimed at improving transmission performance. If selected, between 60-70 of the Bell 412EPI
-based helicopters would be produced locally in Fuji with the first slated to deliver in 2022. Civilian variants would also be produced in Fuji in an effort to help the production line attain scale.
UH-1Y and AH-1Z

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.

Honeywell is working on improving
the T55 turboshaft engine found on the CH-47 Chinook
helicopter. Aimed at increasing its power efficiency by 25%, work has begun on developing a new improved compressor that would increase the T55’s engine power - from 4,700shp (3,500kW) to 6,000shp - and reduce fuel usage by 8%. The research coincides with Boeing's Block 2 upgrade on the helicopter, which aims to increase its lost pay-load capability.
CH-47Fs take off
DII FOCUS articles offer in-depth, updated looks at significant military programs of record; this FOCUS Article covers the CH-47F/MH-47G Chinook helicopter programs, in the USA and abroad. These helicopters’ distinctive “flying banana” twin-rotor design stems from the brilliant work of aviation pioneer Frank Piasecki. It gives Chinooks the ability to adjust their positioning very precisely, while carrying a large airframe whose load capacity has made it the world’s most popular heavy-lift helicopter. The USA expects to be operating Chinooks in their heavy-lift role past 2030.
The CH-47F looks similar to earlier models, but offers a wide range of improvements in almost every aspect of design and performance. While the related HH-47’s $10-15 billion CSAR-X program win was terminated, delivery orders continue for CH-47Fs and for MH-47G Special Forces configuration helicopters. International orders or formal requests have also come in from Australia, Britain, Canada, Italy, the Netherlands, Turkey, and the UAE, with India and other countries expected to follow.

Lockheed Martin is to upgrade
a target acquisition and vision sensor aboard US Army AH-64E
Apache helicopters. The upgrade to the Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor, or M-TADS/PNVS on the AH-64E was commissioned by the Army under a $49 million contract. Lockheed said that under the award it will produce an additional 42 Modernized Day Sensor Assembly upgrade kits and spares for the US Army as part of Lot 1 production at two of its facilities in Florida.
AH-64 in Afghanistan
The AH-64 Apache will remain the US Army’s primary armed helicopter for several more decades, thanks to the collapse of the RAH-66 Comanche program, and the retirement sans replacement of the US Army’s Armed Reconnaissance Helicopter (ARH). Apaches also serve with a number of American allies, some of whom have already expressed interest in upgrading or expanding their fleets.
The AH-64E Guardian Block III (AB3) is the helicopter’s next big step forward. It incorporates 26 key new-technology insertions that cover flight performance, maintenance costs, sensors & electronics, and even the ability to control UAVs as part of manned-unmanned teaming (MUT). In July 2006, Boeing and U.S. Army officials signed the initial development contract for Block III upgrades to the current and future Apache fleet, via a virtual signing ceremony. By November 2011, the 1st production helicopter had been delivered. So… how many helicopters will be modified under the AH-64 Block III program, what do these modifications include, how is the program structured, and what has been happening since that 2006 award? The short answer is: a lot, including export interest and sales.

Saudi Arabia is set to buy a further eight UH-60M Black Hawks
in a $91 million US Army contract. The foreign military sale
will see Sikorsky provide the medium-lift utility helicopters by December 2017. Back in February, Sikorsky and Saudi Arabian firm Taqnia Aeronautics began investigating the possibilities
of producing Black Hawks in the kingdom as part of efforts to diversify their economy amid dropping oil prices.
F-15S & weapons
In October 2010, talks that Saudi Arabia was negotiating a $30-60 billion arms package with the USA were made official with a full multi-billion request that included 84 F-15 Strike Eagles to replace the Kingdom’s Tornado strike aircraft and/or F-15A-D fighters, upgrades for another 70 planes, about 132 UH-60 Black Hawk utility and AH-64 attack helicopters, and armaments to equip them.
This article looks at those requests, their tie-ins, the issues that are part of these potential deals, and related follow-on requests. As is often the case with DSCA announcements, years can pass between the requests and the signed contracts, but these contracts have started to roll in, alongside other significant buys.

The Pakistani-Chinese JF-17
fighter will be making its way to Nigeria after a memorandum of understanding was signed
at this year's AAD. While the exact amount of the fighters has yet to be revealed, further details on the deal are expected to be announced in November during the IDEAS
show in Karachi, Pakistan. Nigerian budget allocations released in January, however, earmarked $25 million for three JF-17s, with approximately half that amount made available for the acquisition of ten PAC Super Mushshak
FC-1/ JF-17, armed
The FC-1/ JF-17 Thunder is a joint Chinese-Pakistani project that aimed to reduce Pakistan’s dependence on western firms for advanced fighters, by fielding a low-cost multi-role lightweight fighter that can host modern electronics and precision-guided weapons. It isn’t a top-tier competitor, but it represents a clear step up from Pakistan’s Chinese MiG-19/21 derivatives and French Mirage III/V fighters. This positioning addresses a budget-conscious, “good enough” performance market segment that the West once dominated, but has nearly abandoned in recent decades.
Pakistan has fielded JF-17s in squadron strength, with more on order and a Block II R&D program nearing completion. India’s competing Tejas fighter is overcoming project delays by looking to foreign component sources, but Pakistan and China remain out front with their offering, even though they began their project much later than India did. Pakistan and China have even set up a joint JF-17 marketing agency to promote export sales, which hasn’t paid off as quickly as they had hoped, but it would be unwise to count them out just yet…

Recommendations for the replacement of the A-10
Warthog are to be expected as soon as September
. While recent reporting on the OA-X
close-air support (CAS) aircraft has leaked some information on the program, it looks likely that USAF will want to acquire two CAS platforms. This would involve a a low flight-hour cost light attack aircraft augmenting the A-10 in the short term, with the service procuring an existing or potential new CAS design. Also on the table are rewinging the A-10 or buying just one replacement platform.
A-10A over Germany
The Precision Engagement modification is the largest single upgrade effort ever undertaken for the USA’s unique A-10 “Warthog” close air support aircraft fleet. While existing A/OA-10 aircraft continue to outperform technology-packed rivals on the battlefield, this set of upgrades is expected to make them more flexible, and help keep the aircraft current until the fleet’s planned phase-out in 2028. When complete, A-10C PE will give USAF A-10s precision strike capability sooner than planned, combining multiple upgrades into 1 time and money-saving program, rather than executing them as standalone projects. Indeed, the USAF accelerated the PE program by 9 months as a result of its experiences in Operation Iraqi Freedom.
This is DID’s FOCUS Article for the PE program, and for other modifications to the A-10 fleet. It covers the A-10’s battlefield performance and advantages, the elements of the PE program, other planned modifications, related refurbishment efforts to keep the fleet in the air, and the contracts that have been issued each step of the way.
