AH-64E Apache Block III: Evolving Battlefield Roles

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.

The JAS-39 Gripen: Sweden’s 4+ Generation Wild Card

As a neutral country with a long history of providing for its own defense against all comers, Sweden also has a long tradition of building excellent high-performance fighters with a distinctive look. From the long-serving Saab-35 Draken (“Dragon,” 1955-2005) to the Mach 2, canard-winged Saab-37 Viggen (“Thunderbolt,” 1971-2005), Swedish fighters have stressed short-field launch from dispersed/improvised air fields, world-class performance, and leading-edge design. This record of consistent project success is nothing short of amazing, especially for a country whose population over this period has ranged from 7-9 million people.

This is DID’s FOCUS Article for background, news, and contract awards related to the JAS-39 Gripen (“Griffon”), a canard-winged successor to the Viggen and one of the world’s first 4+ generation fighters. Gripen remains the only lightweight 4+ generation fighter type in service, its performance and operational economics are both world-class, and it has become one of the most recognized fighter aircraft on the planet. Unfortunately for its builders, that recognition has come from its appearance in Saab and Volvo TV commercials, rather than from hoped-for levels of military export success. With its 4+ generation competitors clustered in the $60-120+ million range vs. the Gripen’s claimed $40-60 million, is there a light at the end of the tunnel for Sweden’s lightweight fighter? In 2013 a win in Brazil started to answer that question.

Israel Announces F-16 Variant Upgrades

F-15s and F-16s make up the backbone of Israel’s potent fighter force. The IDF’s main fighter is the F-16 Fighting Falcon, including aging F-16 A/B Netz (“Falcon”), plus F-16C Barak (“Lightning”) and 2-seat F-16D Brakeets (“Thunderbolt”), and now the heavily customized two-seat F-16I Block 52+ Soufa (“Storm”). The Israelis fly the largest contingent of F-16s outside the United States, alongside longer range, higher performance F-15s. F-15A-D Baz (“Eagle”) models have greatly distinguished themselves in IDF service, and the customized two-seat F-15I Ra’ahm (“Thunder”) Strike Eagle is optimized for advanced ground attack and long range interception. All of these aircraft are heavily modified from the US versions, with Israeli avionics, self-protection systems, weapons, and sometimes radars as well.

While Israel’s F-16A/B Netz inventory may well be sold on the international market, their F-16 C/D and F-15 A-D planes were expected to serve the Air Force Corps until at least 2020. Unfortunately, Israel’s new F-35As won’t even start arriving until 2016 or 2017. To keep their edge, Israel began spending money in 2006 to improve and upgrade its legacy fighter fleet…

Adir Who? Israel’s F-35i Stealth Fighters

In an exclusive June 2006 interview, Israeli Air Force (IAF) chief procurement officer Brigadier-General Ze’ev Snir told Israeli media that the F-35 Joint Strike Fighter was a key part of their IAF recapitalization plans, and that Israel intended to buy over 100 of the fighters to replace their fleet of over 300 F-16s.

Since then, however, the expected cost of that purchase has more than doubled. Israel’s F-35 contract had to deal with that sticker shock, with issues like the incorporation of Israeli technologies and industrial work, and with major schedule slips in the core F-35 program. Israel was even contemplating delaying its purchase, which would have removed an important early adopter for the Lightning II. In the end, however, Israel decided to forego other fighter options, and became the first foreign buyer of operational F-35s. So, how is the “F-35i Adir” shaping up?

Up to $11.9B for B-52H Maintenance & Modernization

Officially, it’s the B-52H Stratofortress. Unofficially, it’s the BUFF (Big Ugly Fat F–cker). Either way, this subsonic heavy bomber remains the mainstay of the U.S. strategic fleet after more than 50 years of service. A total of 102 B-52H bombers were delivered from FY 1961-1963, and 94 were still on the books as of May 2009, flying mostly from Barksdale AFB, LA and Minot AFB, ND. Of these, 18 are slated for retirement, leaving a planned fleet of 76. By the time that fleet retires in the 2030s, many will be around 70 years old.

The B-52H can’t be flown against heavy enemy air defenses, but a steady array of upgrades have kept the aircraft relevant to follow-on strikes and current wars, where its long time on station and precision weapons have made the BUFF beautiful. Those changes have included advanced communications, GPS guided weapons, advanced targeting pods, and more. The USAF isn’t done yet adding new features, and maintenance remains a challenge for an aircraft fleet that’s always older than its pilots. All of these things require contracts, and the B-52H fleet has several of them underway. So, how does 2010’s 8-year, $11.9 billion umbrella contract fit in…?

The C-130J: New Hercules & Old Bottlenecks

The C-130 Hercules remains one of the longest-running aerospace manufacturing programs of all time. Since 1956, over 40 models and variants have served as the tactical airlift backbone for over 50 nations. The C-130J looks similar, but the number of changes almost makes it a new aircraft. Those changes also created issues; the program has been the focus of a great deal of controversy in America – and even of a full program restructuring in 2006. Some early concerns from critics were put to rest when the C-130J demonstrated in-theater performance on the front lines that was a major improvement over its C-130E/H predecessors. A valid follow-on question might be: does it break the bottleneck limitations that have hobbled a number of multi-billion dollar US Army vehicle development programs?

C-130J customers now include Australia, Britain, Canada, Denmark, India, Israel, Iraq, Italy, Kuwait, Norway, Oman, Qatar, Saudi Arabia, South Korea, Tunisia, and the United States. American C-130J purchases are taking place under both annual budgets and supplemental wartime funding, in order to replace tactical transport and special forces fleets that are flying old aircraft and in dire need of major repairs. This DID FOCUS Article describes the C-130J, examines the bottleneck issue, covers global developments for the C-130J program, and looks at present and emerging competitors.

South Korea Launches KF-16 Fighter Upgrades Upended

In July 2009, The Korea Times reported that ROKAF was looking to upgrade its F-16C/D fleet’s radar and armament, as part of the 2010-2014 arms acquisition and management package submitted to President Lee Myung-bak for approval.

Under the Peace Bridge II and II deals, The ROKAF bought 140 “KF-16” Block 52 fighters, which were assembled in Korea between 1994-2004 under a $5.5 billion licensing agreement. Key upgrades to this fleet will include new radars to replace the existing APG-68v5/v7 systems, modern avionics and computers, and upgrades of the planes’ cabling and databuses to MIL-STD-1760. The centerpiece AESA radar competition has a winner now, and South Korea has picked its contractor for the overall upgrade program. Now the effort is turning that into binding contracts, and beginning the upgrade process. Other countries within the region and beyond are interested in similar high-value F-16 upgrade programs, so the ROk’s experiences will be watched carefully.

AN/TPY-2: America’s Portable Missile Defense Radar

The THAAD Ground-Based Radar (GBR), now known as the AN/TPY-2, is an X-Band, phased array, solid-state, long-range air defense radar. It was developed and built by Raytheon at its Andover, MA Integrated Air Defense Facility, as the main radar for the US Army’s THAAD late midcourse ballistic missile defense system.

For THAAD, targeting information from the TPY-2 is uploaded to the missile immediately before launch, and continuously updated in flight via datalinks. The TPY-2 is always deployed with THAAD, but it can also be used independently as part of any ABM (anti ballistic missile) infrastructure. That flexibility, and ease of deployment, is carving out an expanding role for the TPY-2/ “FBX” that reaches beyond THAAD. If a recent NRC report is adopted, that role will expand again to include national-scale ballistic missile defense. Hence this separate article to cover its ongoing development.

Japan Orders Upgrades for its 4 E-767 AWACS

In May 2006, the Defense Security Cooperation Agency notified Congress of a possible Foreign Military Sale to Japan of four sets of Airborne Early Warning (AEW) and Command, Control and Communications (C3) mission equipment/Radar System Improvement Program (RSIP) Group A and B kits, plus spares and services to ensure complete AWACS mission equipment supportability, for subsequent installation and checkout in 4 previously procured E-767 Airborne Warning and Control Systems (AWACS) aircraft.

Boeing delivered the 4 AWACS E-767s to Japan between 1998-1999; they have been in service since 2000.

Support & Smokes for Brazil’s Super Tucanos

Brazil has kicked off the LAAD 2013 expo with a pair of announcements related to their Super Tucano fleet. The first is a 5-year, BRL 252 million (about $127.4 million) contract for Embraer to support the FAB’s 92 remaining “A-29″/EMB-314 Super Tucanos, of the 99 originally purchased. Programa de Suporte Logístico Integrado (PSLI) is a fixed-price contract with performance requirements, mirroring Britain’s recent advances in reducing support costs using “contracting for availability.” PLSI covers materials and planning, supplies for scheduled and unscheduled maintenance, repairs, and overhauls of components, support for the landing gear and propeller groups, and specialized technical support. The basic service package is BRL 223 million, with BRL set aside for unexpected services. Embraer.
