    In a future USAF bomber force, old and ugly beats new and snazzy

    Robert Burns, The Associated Press WHITEMAN AIR FORCE BASE, Mo. — In the topsy-turvy world of U.S. strategic bombers, older and uglier sometimes beats newer and snazzier. As the Air Force charts a bomber future in line with the Pentagon's new focus on potential war with China or Russia, the youngest and flashiest — the stealthy B-2, costing a hair-raising $2 billion each — is to be retired first. The oldest and stodgiest — the Vietnam-era B-52 — will go last. It could still be flying when it is 100 years old. This might seem to defy logic, but the elite group of men and women who have flown the bat-winged B-2 Spirit accept the reasons for phasing it out when a next-generation bomber comes on line. “In my mind, it actually does make sense to have the B-2 as an eventual retirement candidate,” says John Avery, who flew the B-2 for 14 years from Whiteman Air Force Base in western Missouri. He and his wife, Jennifer, were the first married couple to serve as B-2 pilots; she was the first woman to fly it in combat. The Air Force sees it as a matter of money, numbers and strategy. The Air Force expects to spend at least $55 billion to field an all-new, nuclear-capable bomber for the future, the B-21 Raider, at the same time the Pentagon will be spending hundreds of billions of dollars to replace all of the other major elements of the nation's nuclear weapons arsenal. The Air Force also is spending heavily on new fighters and refueling aircraft, and like the rest of the military it foresees tighter defense budgets ahead. The B-2′s viability suffers from the fact that only 21 were built, of which 20 remain. That leaves little slack in the supply chain for unique spare parts. It is thus comparatively expensive to maintain and to fly. It also is seen as increasingly vulnerable against air defenses of emerging war threats like China. Then there is the fact that the B-52, which entered service in the mid-1950s and is known to crews as the Big Ugly Fat Fellow, keeps finding ways to stay relevant. It is equipped to drop or launch the widest array of weapons in the entire Air Force inventory. The plane is so valuable that the Air Force twice in recent years has brought a B-52 back from the grave — taking long-retired planes from a desert “boneyard” in Arizona and restoring them to active service. Strategic bombers have a storied place in U.S. military history, from the early days of the former Strategic Air Command when the only way America and the former Soviet Union could launch nuclear weapons at each other was by air, to the B-52′s carpet bombing missions in Vietnam. Developed in secrecy in the 1980s, the B-2 was rolled out as a revolutionary weapon — the first long-range bomber built with stealth, or radar-evading, technology designed to defeat the best Soviet air defenses. By the time the first B-2 was delivered to the Air Force in 1993, however, the Soviet Union had disintegrated and the Cold War had ended. The plane made its combat debut in the 1999 Kosovo war. It flew a limited number of combat sorties over Iraq and Afghanistan and has launched only five combat sorties since 2011, all in Libya. The last was a 2017 strike notable for the fact that it pitted the world's most expensive and exotic bomber against a flimsy camp of Islamic State group militants. “It has proved its worth in the fight, over time,” says Col. Jeffrey Schreiner, who has flown the B-2 for 19 years and is commander of the 509th Bomb Wing at Whiteman, which flies and maintains the full fleet. But after two decades of fighting small wars and insurgencies, the Pentagon is shifting its main focus to what it calls “great power competition” with a rising China and a resurgent Russia, in an era of stiffer air defenses that expose B-2 vulnerabilities. Thus the Pentagon's commitment to the bomber of the future — the B-21 Raider. The Air Force has committed to buying at least 100 of them. The plane is being developed in secrecy to be a do-it-all strategic bomber. A prototype is being built now, but the first flight is not considered likely before 2022. Bombers are legend, but their results are sometimes regretted. A B-2 bomber scarred U.S.-China relations in 1999 when it bombed Beijing's embassy in the Serbian capital of Belgrade, killing three people. China denounced the attack as a “barbaric act,” while the U.S. insisted it was a grievous error. The Air Force had planned to keep its B-2s flying until 2058 but will instead retire them as the B-21 Raider arrives in this decade. Also retiring early will be the B-1B Lancer, which is the only one of the three bomber types that is no longer nuclear-capable. The Air Force proposes to eliminate 17 of its 62 Lancers in the coming year. The B-52, however, will fly on. It is so old that it made a mark on American pop culture more than half a century ago. It lent its name to a 1960s beehive hairstyle that resembled the plane's nosecone, and the plane featured prominently in Stanley Kubrick's 1964 black comedy, “Dr. Strangelove.” More than once, the B-52 seemed destined to go out of style. “We're talking about a plane that ceased production in 1962 based on a design that was formulated in the late 1940s,” says Loren Thompson, a defense analyst at the Lexington Institute, a Washington think-tank. Rather than retire it, the Air Force is planning to equip the Boeing behemoth with new engines, new radar technology and other upgrades to keep it flying into the 2050s. It will be a “stand off” platform from which to launch cruise missiles and other weapons from beyond the reach of hostile air defenses. In Thompson's view, the Air Force is making a simple calculation: The B-52 costs far less to operate and maintain than the newer but finickier B-2. “They decided the B-52 was good enough,” he says. https://www.airforcetimes.com/news/your-air-force/2020/07/26/in-a-future-usaf-bomber-force-old-and-ugly-beats-new-and-snazzy/

    Babcock to provide helicopters and support for the French Navy

    February 27, 2020 - In a contract led by the French Armament General Directorate (DGA) for the French Navy, Babcock, will work in partnership with Airbus Helicopters (AH) and Safran Helicopter Engines (SHE) to provide four H160 helicopters, helicopter modifications and through-life support. The H160 is a part of the interim fleet which will replace the Alouette III before the Guépard's entry into service. The aircraft will be used by the French Navy on demanding Search and Rescue (SAR) missions and will be based at two locations in North and West France. Babcock is the global launch customer for the H160 helicopter. This 10-year contact commences operations in 2022 and represents a milestone in the French MOD procurement process as it is the first time that a contract includes both hire and purchase of a brand new aircraft and its global support. This contract marks a significant step in Babcock France's deepening collaboration with French military forces after the Jet Fighters Modernized Training Programme (FOMEDEC) signed in 2016 for the French Air Force. It confirms Babcock's military air expertise and commitment to support France's armed forces. Military Aviation Director for Babcock France, Pierre Basquin said: “We are very proud to be part of this innovative project with our partners. All together, we will provide both the H160 to the French Navy with a high level of availability and allow the DGA to prepare for the entry into service of the Guépard.” Working closely with the DGA, Navy, AH and SHE stakeholders, Babcock is now driving forward with mobilisation activities. With a strong framework already in place, we will ensure the customer's faith in our trusted to deliver culture is well placed. Babcock Aviation is focused on defence and emergency services operations. Our mission is to save lives, protect communities and support the defence of nations.

  • No F-35 For You: The French Air Force's New Rafale Fighter Won't Be Stealthy

    No F-35 For You: The French Air Force's New Rafale Fighter Won't Be Stealthy

    by Sebastien Roblin Key point: Paris wants new planes, but it has no plans to build or buy its own stealth fighters. In January 2019, French Defense Minister Florence Parly announced France would commit $2.3 billion to develop an F4 generation of the Dassault Rafale twin-engine multirole fighter. This would include production in 2022–2024 of the last twenty-eight of the original order of 180 Rafales, followed by the purchase of an additional thirty Rafales F4.2s between 2027–2030, for a total of 210. Since 2008, France has deployed land- and carrier-based Rafales into combat in Afghanistan, Iraq, Libya, Mali and Syria. In January 2019, French Defense Minister Florence Parly announced France would commit $2.3 billion to develop an F4 generation of the Dassault Rafale twin-engine multirole fighter. This would include production in 2022–2024 of the last twenty-eight of the original order of 180 Rafales, followed by the purchase of an additional thirty Rafales F4.2s between 2027–2030, for a total of 210. Since 2008, France has deployed land- and carrier-based Rafales into combat in Afghanistan, Iraq, Libya, Mali and Syria. The Rafale is much more agile than the F-35, with superior climb rate, sustained turn performance, and ability to super-cruise (maintain supersonic flight without using fuel-gulping afterburners) at Mach 1.4 while carrying weapons. The Rafale's all-moving canards—a second set of small wings near the nose—give the Rafale excellent lift and low-altitude speed and performance, as you can see in this majestic airshow display. However, compared to larger fourth-generation twin-engine jets like the Su-35 or F-15, the Rafale can't fly quite as high (service-ceiling of 50,000 instead of 60,000 ft), and has a lower maximum speed (only Mach 1.8 compared to Mach 2-2.5). The Rafale's agility won't help as much if it is engaged at long distances by enemy surface-to-air missiles and stealth jets. To compensate, the Rafale boasts an advanced Spectra electronic warfare system that supposedly can reduce the Rafale's cross-section several times over—it is rumored by reflecting back signals using ‘active canceling.' Spectra also incorporates powerful jammers and flare and chaff dispensers, provides 360-degree early-warning, and can even assist Rafale pilots in targeting weapons to retaliate against attackers. Spectra's capabilities reportedly allowed Rafales to deploy on raids over Libyan airspace in 2011 before air defense missiles had been knocked out. Other key capabilities include sensor fusion of the Rafale's RBE-2AA Active Electronically Scanned Array multi-mode radar, which can track numerous targets over 124 miles away, with its discrete OSF infrared-search and track system, which has an unusually long range of sixty-two miles. Rafale pilots also benefit from uncluttered instrumentation combining voice command with flat-panel touch screens. The multirole jet carries a punchy thirty-millimeter revolver cannon and up to twenty-one thousand pounds of weapons on fourteen hardpoints, making it a versatile air-to-ground platform. Because Paris requires expeditionary capability in Africa, the Rafale can refuel in flight and carry up to five fuel tanks for very long transits, and can be operated from relatively unprepared airfields, unlike most high-performance jets. What's new in the Rafale F4? Dassault produces three basic types of Rafales: the single-seat Rafale-C, the two-seat Rafale-B (the additional weapon systems officer being preferred for strike and reconnaissance missions) and the carrier-based single-seat Rafale-M, which has an arrestor hook, reinforced landing gear and buddy-refueling pod capability. Each type has evolved in common generations designated F1, F2, F3 and F3R. The F4 generation introduces additional network-centric warfare capabilities and data-logistics similar to those on the F-35 Lightning, enabling Rafales on patrol to build a more accurate picture of the battlespace by pooling their sensors over a secure network, and even exchange data using new satellite communications antenna. The pilots also benefit from improved helmet-mounted displays. The Spectra defensive system will receive more powerful jammers and new threat libraries tailored to meet the improving capabilities of potential adversaries. Furthermore, Dassault seeks to use “Big Data” technology to develop a predictive maintenance system reminiscent of the F-35's troubled ALIS system to cost-efficiently implement preventative repairs. Other systems to be tweaked include the air-to-ground mode of the RBE-2AA radar, the M88 turbofan's digital computers, and a new AI-system for its reconnaissance and targeting pod allowing it to rapidly analyze and present information to the pilot. Rafale-Ms will also receive a new automated carrier landing system. New weapons set for integration most notably an improved model of the Mica short-to-medium range air-to-air missile, which has a range of forty-nine miles. The Mica can be launched without initially being locked and guided remotely by a data link on the fighter before engaging either an infrared or AESA radar seeker to close in for the kill, using a vector-thrust motor to pull off tight maneuvers. Because both the Rafale and the Mica missile can employ passive infrared targeting without using an indiscrete active-radar for guidance, the MICA can be launched with little warning for the target. The Mica-NG model will incorporate new infrared-matrix sensors for better performance versus stealth fighters, carry additional propellant for longer range, and integrate internal sensors to reduce maintenance costs. Its dual pulse motor will allow it to accelerate just prior to detonation for a greater probability of achieving a kill. For longer range engagements, newer Rafales F3Rs and F4s can launch British Meteor missiles which can sustain Mach 4 speeds. Another weapon set for integration is heavier 2,200-pound variants of the AASM HAMMER, a guidance kit similar to the U.S. JDAM. Previously, the Rafale could only carry 485-pound variants of the weapon which can use either GPS-, laser- or -infrared guidance to deliver precise strikes. Unlike the JDAM, the HAMMER also incorporates a rocket-motor, allowing it to hit targets up to thirty-seven miles away when released at high altitude. The Rafale will also be modified to integrate future upgrades of the French SCALP-EG stealthy subsonic cruise missile and the supersonic ASMP-A cruise missile which carries a 300-kiloton-yield nuclear warhead. Reportedly France may develop a hypersonic AS4NG variant increasing range from 300 miles to over 660 miles. Currently, the French Armée de l'Aire has three Rafale multi-role squadrons and two nuclear-strike squadrons based in Mont-de-Marsan (south-western France), Saint-Dizier (north-eastern France) and al-Dhafra in the UAE. There are also an operational conversion unit and a testing and evaluation squadron. The French Navy has three Rafale-M squadrons which rotate onboard France's nuclear-powered carrier Charles de Gaulle. In 2018, a squadron of Rafale-Ms proved their capability to operate from the U.S. carrier George H. W. Bush. The forthcoming Rafale F4s will progressively replace France's fourth-generation Mirage 2000s, over 110 of which remain in service today. French periodical Le Figaro claims that older Rafales will also eventually be updated to the F4 standard. Abroad, Dassault is finish delivery of orders from Egypt (twenty-four), Qatar (thirty-six) and India (thirty-six). All three countries may order additional Rafales, though the price of its initial Rafale order has caused a political scandal in New Delhi. As France must wait nearly two decades before a European stealth fighter can enter service, its armed forces are betting that in the interim adding networked sensors and weapons to the Rafale's superior kinematic performance and powerful electronic warfare systems will keep the agile jet relevant in an era of proliferating stealth aircraft and long-range surface-to-air missiles.
