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.

Sons of Sa’ar? Israel’s Next Generation Frigates

The 1,227t/ 1,350 ton Sa’ar 5 Eilat Class corvettes were built by Northrop Grumman in the 1990s for about $260 million each. It’s a decent performer in a number of roles, from air defense to anti-submarine work, to coastal patrol and special forces support. In 2006, the Israelis went looking for a next-generation vessel with better high-end capabilities. Six years later, Israel had nothing to show for its search. In the meantime, massive natural gas deposits have been discovered within Israel’s coastal waters, adding considerable urgency to their search.

The USA is Israel’s logical supplier, but given Israel’s size and cost requirements, the only American option was the Littoral Combat Ship. Israel pursued that option for several years, conducting studies and trying to get a better sense of feasibility and costs. Their approach would have been very different from the American Freedom Class LCS, removing the swappable “mission modules” and replacing them with a fixed and fully capable set of air defense, anti-ship, and anti-submarine weapons. In the end, however, the project was deemed to be unaffordable. Instead, Israel began negotiating with Germany, and reports now include discussions involving both South Korea, and a local shipyard.

KC-46A Pegasus Aerial Tanker Completes Firsts

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

The Wonders of Link 16 For Less: MIDS-LVTs

What one sees, all see. Jam-resistant Link-16 radios automatically exchange battlefield information – particularly locations of friendly and enemy aircraft, ships and ground forces – among themselves in a long-range, line-of-sight network. For example, air surveillance tracking data from an Airborne Warning and Control System (AWACS) aircraft can be instantly shared with fighter aircraft and air defense units. More than a dozen countries have installed Link 16 terminals on over 19 different land, sea, and air platforms, making it an interoperability success story.

While recent advancements may make AESA radars the future transmitters of choice, Link 16 is the current standard. The Multifunctional Information Distribution System-Low Volume Terminals (MIDS LVTs) were developed by a multinational consortium to provide Link 16 capability at a lower weight, volume, and cost than the Joint Tactical Information Distribution System (JTIDS). This free-to-view DID Spotlight article throws a spotlight on the program, explaining Link 16, and covering associated contracts around the world.

JDAM: A GPS-INS Add-on Adds Accuracy to Airstrikes

Precision bombing has been a significant military goal since the invention of the Norden bomb sight in the 1920s, but its application remained elusive. Over 30 years later, in Vietnam, the destruction of a single target could require 300 bombs, which meant sending an appropriate number of fighters or bombers into harm’s way to deliver them. Even the 1991 Desert Storm war with Iraq featured unguided munitions for the most part. The USAF some laser and TV-guided weapons like Paveway bombs and Maverick missiles, but they were very expensive, and only effective in good weather. If precision bombing was finally to become a reality throughout the Air Force, a new approach would be needed. The Joint Direct Attack Munition (JDAM) became that alternative, an engine of military transformation that was also a model of procurement transformation.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This DID FOCUS Article looks at the transformational history of the JDAM GPS-guided bomb program, the ongoing efforts to bring its capabilities up to and beyond the level of dual-mode guidance kits like Israel’s Spice and Raytheon’s Enhanced Paveway, and the contracts issued under the JDAM program since its inception.[updated]

Submarines for Indonesia

Indonesia sites astride one of the world’s most critical submarine chokepoints. A large share of global trade must pass through the critical Straits of Malacca, and the shallow littoral waters around the Indonesian archipelago. That makes for excellent submarine hunting grounds, but Indonesia has only 2 “Cakra Class”/ U209 submarines in its own fleet, relying instead on frigates, corvettes, and fast attack craft.

South Korea’s Daewoo, which has experience building U209s for South Korea, has been contracted for Cakra Class submarine upgrades. Even so, submarine pressure hulls have inflexible limits on their safe lifetime, due to repeated hydraulic squeezing from ascending and descending. The Indonesians have expressed serious interest in buying 3-6 replacement submarines since 2007, with French, German, Russian, South Korean, and even Turkish shipyards in the rumored mix. Other priorities shoved the sub purchase aside, but a growing economy and military interest finally revived it. South Korea was the beneficiary, but further orders may be in store.

Korean Air Refueling: Airbus Wins

South Korea is moving to buy 4 long-range aerial refueling tankers with secondary transport capabilities, with a budget of WON 2 billion (about $1.8 billion). That capability isn’t a huge priority on the Korean peninsula itself, but it’s very useful for international operations. It’s useful as a way of projecting regional power, as territorial disputes flare with China.

As Asian economies grow and militaries modernize, these factors have made long-range aerial refueling a growing regional priority. China, India, Pakistan and China deploy the Russian IL-78. Japan fields 4 Boeing KC-767As, and may raise that to 8 under recent plans. Similar American KC-46As will join them in the region after 2017. Elsewhere in the region, Australia (5) and Singapore (4) picked Airbus Defense & Space’s larger A330 MRTT instead, and India looks set to buy 6 at some point. What will the ROKAF do?

US Hellfire Missile Orders, FY 2011-2018

Hellfire I/II missiles are the USA’s preferred aerial anti-armor missile, and are widely deployed with America’s allies. They equip America’s helicopter fleets (AH-64, AH-1, OH-58D, MH-60S/R), AH-64 and S-70 helicopters flown by its allies, and even Australia and France’s Eurocopter Tiger attack helicopters. Range is officially listed as 9 km/ 5.6 miles.

While Hellfires lack the fast-jet launch capabilities – and correspondingly extended maximum range – of the UK’s MBDA Brimstone missiles, Lockheed Martin’s missile has made big inroads as the world’s high-end helicopter-launched missile. It has also carved out unique niches as tripod-launched coastal defense assets, as the guided missile integrated into American UAVs like the MQ-1 Predator family, and even as a missile option for transport aircraft like the AC-208B Combat Caravan and C-130J/W Hercules.

Turkey & South Korea’s Altay Tank Project

Turkey’s tank fleet is currently made up of American M-48s and M-60s, some of which have been modernized with Israeli cooperation into M-60 Sabra tanks, plus a large contingent of German Leopard 1s and Leopard 2s. That is hardy surprising. America and Germany are Turkey’s 2 most important geopolitical relationships, and this is reflected in Turkey’s choice of defense industry partners. The country’s industrial offset requirements ensure that these manufacturers have a long history of local partnerships to draw upon.

In recent years, however, a pair of new players have begun to make an impact on the Turkish defense scene. One was Israel, whose firms specialized in sub-systems, upgrades, and UAVs. The other is the Republic of [South] Korea, who has made inroads in the Turkish market with turboprop training aircraft, mobile howitzers… and now, main battle tanks.

Korea’s New Coastal Frigates: the FFX Incheon Class

South Korea currently owns some of the world’s best and most advanced shipyards. That civilian strength is beginning to create military leverage, and recent years have seen the ROK take several steps toward fielding a true open-ocean, blue water navy. Their new KDX-II destroyers, KDX-III AEGIS destroyers, LPX amphibious assault ships, and KSS-I/KSS-II (U209/U214) submarines will give the nation more clout on the international stage, but what about the home front? North Korea’s gunboats have launched surprise attacks on the ROK Navy twice in the last decade, while its submarines continue to insert commandos in South Korean territory, and committed acts of war by sinking ROKN ships. To the west, Chinese fishing rights are a contentious issue that has led to the murder of a Korean Coast Guard official on the high seas.

Hence the Future Frigate Experimental (FFX) program. It aims to build upon lessons learned from ROK naval shipbuilding programs in the 1980s and 1990s, and replace 37 existing ships with a modern class of upgunned inshore patrol frigates. A contract to build the lead FFX frigate Incheon was issued in December 2008, and South Korea continues to work to define the program, including the forthcoming Batch II design.
