On June 12, the U.S. State Department approved a Foreign Military Sale to India of six AH-64E Apache attack helicopters. The contract carries a potential value of $930 million. The contract also covers a host of specialized mission electronics, including the APG-78 Longbow fire control radar and M-TADS/PNVS electro-optical system. Continue reading
Multiple companies have recently been awarded contracts for international AH-64 retrofit programs. As one of the world’s premier attack helicopters, the Apache is well funded, and is upgraded regularly with new and improved technologies. Continue reading
The Netherlands has received approval from the U.S. State Department for the upgrade and remanufacture of its AH-64D Block II Apache attack helicopters to the AH-64E configuration. While the contract would largely entail work on the helicopter itself, it would also include the replacement of many of the helicopters’ primary electronics systems. The overall deal carries an estimated value of $1.191 billion. Continue reading

Recent reports of significant layoffs by Boeing have proven to be of little concern to Wall Street investors, who shrugged those actions off as an efficiency move. Not only that, Boeing stock rose dramatically to a new high last week, and during a two-day period jumped 28 points, sending the Dow Jones Average to a new all-time high. Continue reading
Van Horn Aviation recently celebrated the first installation and flight of VHA composite main rotor blades on its launch customer, Hummingbird Helicopter’s 206B. According to Van Horn Aviation, Bob Hoag, owner of Hummingbird Helicopters, is a current customer of Van Horn’s composite tail rotor blades, and was eager to be the launch customer for the main blade.
Composite materials have been developed and refined over the years for use on fixed wing aircraft and helicopters. Helicopter rotor blades perhaps benefit most from composite materials due to increases in fatigue resistance and higher strength-to-density ratios.
Among other major worldwide composite rotor blade modernization retrofit efforts is the US Army’s AH-64E Apache Reman program, which includes installation of composite main rotor blades and composite stabilators. The composite main rotor blade is 6 inches longer than the previous blade, with a new tip design to improve aerodynamic performance.
As part of the Chinook Block II upgrade, new composite rotor blades will add 2,000 additional pounds of lift capacity. The program has already made wind tunnel testing progress and was slated for flight testing in summer 2015.
Carson Helicopters provides the composite rotor blades used in Sikorsky’s S-61T conversion program, and markets the FireKing firefighting conversion. Carson is continuing with structural testing and manufacturing process improvements until FAA certification is complete.
Mil’s Mi-35M conversion package offers composite rotor blades, as does Paramount on its Superhind Mk IV and MkII upgrades.
In March 2013, Bell Helicopter signed a Memorandum of Understanding (MoU) with Van Horn Aviation to produce the tail rotor blades for 412 and 212 helicopters, which operators may purchase and install on their own. Van Horn Aviation currently offers UH-1 Huey composite tail rotors, along with its other products, to include the new 206B composite main rotor blade.
“Our newly certificated 206B main rotor blade is the culmination of more than five years of design, prototyping, and testing, including extensive flight and fatigue testing,” said VHA CEO James Van Horn, who designed the blades and flew as copilot/flight test engineer during most of the certification flight testing. “Our goal was to produce composite main rotor blades that would reduce operator cost and increase durability. During flight testing, we saw and felt some improvements in responsiveness with the composite blades compared to the metal blades. We believe the JetRanger operators will be pleased with our composite blades.” – James Van Horn
In February 2016, Van Horn Aviation received Supplemental Type Certification from the U.S. Federal Aviation Administration (FAA) for 206B composite main rotor blades. The blades were approved for 18,000 hours of service life, more than triple that of OEM metal blades. The blades consist of carbon-fiber skin and spars, a laminar-flow airfoil, and a tapered tip. Also, there is a combination of stainless steel and nickel abrasion strips across the entire length of the blade for erosion and lighting strike protection.
“We put the main blade, root, inboard and outboard sections through months of fatigue testing,” said VHA President Dean Rosenlof. “Composites are inherently durable and resist fatigue throughout normal flight parameters, so we tested the blades with simulated hail damage, induced manufacturing defects, and various extreme repairs. We won’t say that the blades are bullet-proof, but they’re close.” – Dean Rosenlof
The blades have an 18,000 hour service life with overhauls required every 2,800 hours. The list price for the blades is $79,500, sold exclusively through Aeronautical Accessories.
Van Horn Aviation is also developing 206L composite main rotor blades, projected to receive an STC in 2017. The 206L blades will be about 22 inches longer, and will have a service life of 25,000 hours.

Forecast International’s Airborne Retrofit & Modernization Forecast provides operators in the military and commercial aviation sectors with the information they need to maximize their current investments rather than expand their fleets, a trend that is opening up multiple opportunities for the expansion of retrofit and modernization programs. It offers a one-stop service for tracking the status of commercial and military R&M programs in progress worldwide, and pinpoints key developments in the aviation industry that will impact the market in the future.
Access to real-time video is a crucial aspect of reconnaissance operations, providing key battlefield intelligence by identifying adversaries and their assets. As such, sales opportunities abound for Lockheed Martin’s VUIT-2 (Video from Unmanned aircraft for Interoperability Teaming-Level 2) system, which has been available since 2009. This kit-based system enables Apache helicopter aircrews to view streaming video and metadata from unmanned aerial systems (UAS). The system also gives Apaches the ability to receive video from aircraft equipped with advanced targeting pods (ATPs). Continue reading
A long-awaited move by the U.K. Ministry of Defence regarding attack helicopter capability has now played out, as a government-to-government request for the upgrade/remanufacture of the British Army fleet of WAH-64D Apaches was approved by the U.S. State Department. Continue reading
