    India Prepares For New Fighter Tender

    by Reuben F. Johnson While it is hard to believe, next year will mark almost 15 years since the Indian Air Force (IAF) embarked on a process to procure a new fighter. It will also be eight years since the force selected the Dassault Rafale for its Medium-Multirole Combat Aircraft (M-MRCA) program—a selection that was eventually not carried through to a license-production run as originally planned. The M-MRCA effort was planned for a procurement of 126 fighters by the IAF with an option for 63 additional units. All but 18 of these aircraft were to be license-assembled in India on a Hindustan Aeronautics Ltd (HAL) production line. In 2012, India eventually selected the Dassault Rafale from a competition that included Russia's Mikoyan MiG-35, the Saab JAS-39E from Sweden, the Eurofighter, and both the Boeing F/A-18E/F Super Hornet and a developed version of the Lockheed Martin F-16. The latter two are U.S. products. REPLACEMENT CRISIS However, in “winning a competition” such as this, a French industry official told AIN, “you do not really ‘win' anything. What you supposedly win is the right to then sit down and negotiate a contract—and if you cannot come to some agreement, then you get nothing after having spent tens of millions [of dollars] for all the years it takes to bid a major program in a place like India.” By 2015 the two sides had not come to an agreement on localized production, and in 2016 the new government of prime minister Narendra Modi ordered 36 Rafales “off-the-shelf,” the first of which has already been officially handed over to India. Seven of the aircraft should be delivered to the IAF between April and May 2020. This, however, still leaves the force woefully short of the force levels it says are needed to meet New Delhi's national security requirements. There is still no suitable replacement for the older (but modernized) MiG-21 Bison aircraft in service. There is also no solution to address the gap created by the 2018 Indian decision to withdraw from the HAL/Sukhoi joint program with Russia for a Future Generation Fighter Aircraft (FGFA) program. India was to have purchased 127 of this aircraft, which would have been a heavily-modified version of the Sukhoi Su-57. After an IAF inspection of one of the program's prototypes, the force was calling for 43 major changes to the design to correct what it saw as deficiencies with the original configuration. VERSION 2.0 The consequence is that India—after some twists and turns—is on a path to issue another tender for what will be at least 100 of some aircraft to fill the void created by these developments. Originally, the program was to have been a competition for only single-engine airplane designs, which would have limited the competition to the JAS-39 and the F-16. The latter has now been re-christened the “F-21,” due to all of the changes that have been made to the design to accommodate Indian requirements. One of the changes was to add a probe-and-drogue refueling option in addition to the traditional USAF flying boom refueling method. This “single-engine only” competition was then widened to allow all of the twin-engine aircraft that participated in the original M-MRCA tender—with Russia's Sukhoi Su-35 now also thrown into the mix. This has prompted more than one observer to dub the still-officially unannounced re-running of the tender as “M-MRCA ver 2.0.” NEEDED: A SHORTER ACQUISITION CYCLE What makes this impending competition all the more critical for India's future defense posture is that the next-generation of aircraft carriers that will be coming online with the Indian Navy that will require a force of CATOBAR (catapult-assisted take-off barrier-arrested recovery) fighter aircraft. Both the Rafale-M and Boeing's Super Hornet are available for this mission and Saab has a design for a carrier-capable Maritime Gripen variant of the JAS-39E on the shelf that can be realized within a short time frame. What remains to be seen is whether or not a new tender can be carried out without making it a repeat of the arduous seven-year process that the original M-MRCA turned out to be. Suggestions had been made last year that a new tender could be carried out without an extensive set of flight trials to shorten the evaluation and down-select cycles. While there is no agreement on which aircraft type or types fit the requirements of both the IAF and the Indian Navy, there are numerous observers both inside and outside of India who disparage the manner in which the selection of a new fighter type has been carried out. “As it stands now, the methodology for buying a new fighter is an objectively dysfunctional process,” said one Indian aerospace expert. “The problem is that it will never change as long as the OEMs keep rewarding those who propagate that process without demanding that it change.” https://www.ainonline.com/aviation-news/defense/2020-02-06/india-prepares-new-fighter-tender

    Le plan de l'armée française pour réduire son empreinte carbone

    La ministre des Armées, Florence Parly, a présenté vendredi la nouvelle « stratégie énergétique de défense » des Armées. Parmi les mesures annoncées figurent notamment le lancement d'un démonstrateur de blindé hybride de modèle Griffon en 2022, ou le développement de la simulation pour les séances d'entraînement dans l'armée de l'Air afin d'économiser du kérosène. Les systèmes d'hébergement de données informatiques vont de plus être revus pour tenter de réutiliser la chaleur des réseaux pour des infrastructures des Armées. Des recherches sur l'hydrogène sont également programmées, notamment pour équiper les piles à combustibles des soldats ou trouver des minidrones propulsés à l'hydrogène. D'ici fin 2021, un logiciel mesurant précisément les consommations énergétiques de toutes les emprises des Armées devrait par ailleurs être disponible. Les Echos du 3 juillet

    Future Missile War Needs New Kind Of Command: CSIS

    Integrating missile defense – shooting down incoming missiles – with missile offense – destroying the launchers before they fire again – requires major changes in how the military fights. By SYDNEY J. FREEDBERG JR.on July 07, 2020 at 4:00 AM WASHINGTON: Don't try to shoot down each arrow as it comes; shoot the archer. That's a time-honored military principle that US forces would struggle to implement in an actual war with China, Russia, North Korea, or Iran, warns a new report from thinktank CSIS. New technology, like the Army's IBCS command network – now entering a major field test — can be part of the solution, but it's only part, writes Brian Green, a veteran of 30 years in the Pentagon, Capitol Hill, and the aerospace industry. Equally important and problematic are the command-and-control arrangements that determine who makes the decision to fire what, at what, and when. Today, the military has completely different units, command systems, doctrines, and legal/regulatory authorities for missile defense – which tries to shoot down threats the enemy has already launched – and for long range offensive strikes – which could keep the enemy from launching in the first place, or at least from getting off a second salvo, by destroying launchers, command posts, and targeting systems. While generals and doctrine-writers have talked about “offense-defense integration” for almost two decades, Green says, the concept remains shallow and incomplete. “A thorough implementation of ODI would touch almost every aspect of the US military, including policy, doctrine, organization, training, materiel, and personnel,” Green writes. “It would require a fundamental rethinking of terms such as ‘offense' and ‘defense' and of how the joint force fights.” Indeed, it easily blurs into the even larger problem of coordinating all the services across all five domains of warfare – land, sea, air, space, and cyberspace – in what's known as Joint All-Domain Operations. The bifurcation between offense and defense runs from the loftiest strategic level down to tactical: At the highest level, US Strategic Command commands both the nation's nuclear deterrent and homeland missile defense. But these functions are split between three different subcommands within STRATCOM, one for Air Force ICBMs and bombers (offense), one for Navy ballistic missile submarines (also offense), and one for Integrated Missile Defense. In forward theaters, the Army provides ground-based missile defense, but those units – Patriot batteries, THAAD, Sentinel radars – belong to separate brigades from the Army's own long-range missile artillery, and they're even less connected to offensive airstrikes from the Air Force, Navy, and Marine Corps. The Navy's AEGIS system arguably does the best job of integrating offense and defense in near-real-time, Green says, but even there, “different capabilities onboard a given ship can come under different commanders,” one with the authority to unleash Standard Missile interceptors against incoming threats and the other with the authority to fire Tomahawk missiles at the enemy launchers. This division of labor might have worked when warfare was slower. But China and Russia have invested massively in their arsenals of long-range, precision-guided missiles, along with the sensors and command networks to direct them to their targets. So, on a lesser scale, have North Korea and Iran. The former deputy secretary of defense, Bob Work, warned of future conflicts in which “salvo exchanges” of hundreds of missiles – hopefully not nuclear ones – might rocket across the war zone within hours. It's been obvious for over a decade that current missile defense systems simply can't cope with the sheer number of incoming threats involved, which led the chiefs of the Army and Navy to sign a famous “eight-star memo” in late 2014 that called, among other things, for stopping enemy missiles “left of launch.” But that approach would require real-time coordination between the offensive weapons, responsible for destroying enemy launchers, command posts, and targeting systems, and the defensive ones, responsible for shooting down whatever missiles made it into the air. While Navy Aegis and Army IBCS show some promise, Green writes, neither is yet capable of moving the data required among all the users who would need it: Indeed, IBCS is still years away from connecting all the Army's defensive systems, while Aegis only recently gained an offensive anti-ship option, a modified SM-6, alongside its defensive missiles. As two Army generals cautioned in a recent interview with Breaking Defense, missile defense and offense have distinctly different technical requirements that limit the potential of using a single system to run both. There are different legal restrictions as well: Even self-defense systems operate under strict limits, lest they accidentally shoot down friendly aircraft or civilian airliners, and offensive strikes can easily escalate a conflict. Green's 35-page paper doesn't solve these problems. But it's useful examination of how complex they can become. https://breakingdefense.com/2020/07/future-missile-war-needs-new-kind-of-command-csis/
