La disponibilité des aéronefs en 2018

Helen Chachaty

En réponse à une question du député François Cornut-Gentille, le ministère des Armées a publié les chiffres actualisés du taux de disponibilité des différentes flottes exploitées par l'armée de l'air, la marine nationale et l'armée de terre. Si certaines font figure de « bonnes élèves » et enregistrent une hausse constante ces trois dernières années, d'autres en revanche, continuent de plonger.

Du côté des voilures fixes, la flotte de transport gouvernemental affiche une disponibilité au beau fixe, relativement constante depuis trois ans : Les A310/330/340 culminent respectivement à 73%, 81,5% et 88,7% de disponibilité, quand les Falcon 7X sont à 71,4% et les Falcon 2000 à 77,8%. Le dernier-né de la flotte, l'A330 MRTT, dont l'affichage du taux risque de disparaître avec son entrée dans le contingent dédié à la dissuasion nucléaire, il enregistre une disponibilité de 66,2% depuis son entrée dans les forces en octobre 2018.

Toujours côté transport, les deux C-130J, réceptionnés fin 2017 et en 2018, affichent un score très respectable de 75,6%. La situation de l'A400M est certes loin d'être florissante, mais le taux de disponibilité est en hausse constante depuis 2016, passant ainsi de 13% à 25,6%, atteignant en 2018 un taux de 27,5%. Les CN235 restent constants sur les trois dernières années, autour de 50%, avec un léger rebond en 2018, pour atteindre les 53,7%. Quant aux C-130H, leur taux de disponibilité continue de baisser (19,4% en 2018), en attendant les effets bénéfiques du changement de prestataire de MCO.

Côté aviation de chasse, les Rafale (air et marine) affichent un taux respectable de 53,6 et 53,7%, soit quasiment 20 points de plus que les Mirage 2000D, dont le taux de disponibilité est passé de 36,3% en 2017 à 33,8% en 2018. La flotte de MQ-9 Reaper, après avoir enregistré une baisse entre 2016 et 2017 en ayant chuté de près de 10 points (de 71,4% à 62,6%), est remontée en 2018 à 73,7% de disponibilité.

Pour les voilures tournantes, ce sont la Gazelle et... la vénérable Alouette III qui tiennent le haut du pavé, affichant respectivement des taux de disponibilité de 46,2 et 44,7%. Ces flottes sont suivies de peu par les Dauphin (43,5%), le Caracal (40%), le Panther (39,9%) et le Fennec (38,65%). En bas de classement, le Lynx, qui atteint à peine les 15,5%. Quant au Tigre HAD (30,2%), il est légèrement devant la version HAD (28,1%). La version marine du NH90 se situe quant à elle cinq points en dessous (30,4%) de la version terrestre (35,5%).

    US Army solicits bids for new cryptographic technologies

    by Carlo Munoz The US Army is soliciting industry proposals to develop new cryptographic technologies, designed to ensure secure and compartmentalised communication capabilities in the wake of rapidly advancing cyber warfare and electronic warfare threats to those operations. The proposals being sought by the service's Program Manager Tactical Radios (PM TR), under Program Executive Office Command, Control, Communicate – Tactical (PEO C3T), will assist in the development of the advanced variant of the Next Generation Load Device-Medium (NGLD-M). Army officials anticipate developing and fielding a maximum of 265,000 NGLD-M units, at an estimated cost of USD850 million, according to the service's 18 November request for proposals (RFP). The new NGLD-M systems will replace the army's more than decade-old fleet of Simple Key Loaders (SKLs), which are designed to transfer, issue, fill, and manage electronic cryptographic keys to highly sensitive End-Cryptographic Units (ECUs), used by combat units to transmit and receive secure communications transmissions. Designed to meet the Type 1 cryptologic standards for secured data transmissions established by the National Security Agency (NSA), the NGLD-M will provide “the functionality of legacy fill devices while providing network connectivity to support Over the Network Key (OTNK) distribution”, the RFP stated. The new NGLD-M will also provide end users with a “reprogrammable crypto subcomponent to meet future modernisation requirements”, it added. “The NGLD-M will enable delivery of the strongest NSA-generated cryptographic keys to tactical, strategic, and enterprise network systems operating from secret to the highest levels of security classification,” according to a PEO C3T statement, issued shortly after the RFP's release. https://www.janes.com/defence-news/news-detail/us-army-solicits-bids-for-new-cryptographic-technologies
