Maintenant, maintenant... crédit de Boeing.

Ils ont fait un travail absolument fantastique sur le KC-46.

Merde... Je ne peux même pas * taper* ça avec un visage droit.

Est-ce que le KC-46 est le tanker avec le problème FOD tout droit sorti de l'usine, ou celui avec la flèche défectueuse? C'est difficile de garder une trace de ces choses...

Des échecs critiques si graves que le CINC d’AMC a essayé de la tuer.

Mais... Le Congrès et les intérêts particuliers étaient un peu trop profonds pour que cela se produise.

À la fin de 2023, l’OTAN a annoncé un plan pour remplacer leur avion AWACS E-3A vintage par six Boeing E-7A Wedgetails. Cette année, ils ont réexaminé cette décision et prévoient maintenant de remplacer les E-3 par jusqu’à dix avions d’alerte précoce et de contrôle aéroportés SAAB GlobalEye. Le GlobalEye est basé sur la cellule Bombardier 6000/6500 et l’OTAN espère prendre livraison du GlobalEye et retirer le E-3 dès 2030.

La mission aéroportée d'alerte et de contrôle a été la première opération conjointe des membres de l'OTAN et remonte à 1982, lorsque les premiers E-3A ont été livrés.

Au cours des décennies qui ont suivi, les membres de l'OTAN ont considérablement élargi les opérations conjointes d'aéronefs:

- Une force prévue de 12 Airbus A330 MRTT transportant des ravitailleurs basés aux Pays-Bas et en Allemagne et exploités par 9 pays membres de l'OTAN.

- Une unité de 3 transports C-17A basée en Hongrie et exploitée par 12 pays membres

- Une force multinationale de transports Airbus A400M opérée par 7 pays membres. Cette force ne possède aucun avion ; les A400M sont mis à disposition par les forces aériennes des États membres.

- Une unité avec 5 gros UAV RQ-4D Phoenix basée à Sigonella, en Sicile, et désignée comme la Force de renseignement, de surveillance et de reconnaissance de l'OTAN. La charge utile principale du RQ-4D est un radar de surveillance au sol avancé.

-- Il vient d'être annoncé cette année, une unité avec jusqu'à 5 drones de surveillance maritime MQ-4C Triton. Les membres participants sont le Danemark, la Finlande, l’Allemagne et la Norvège. Les détails concernant le moment et le lieu d'exploitation ne sont pas encore clairs, mais compte tenu des participants, je m'attendrais à un site d'exploitation en Europe du Nord.

Il convient d'ajouter que la base ci-dessus est flexible; les avions peuvent être déployés à divers endroits.

Longtemps, mais vaut la montre

Tu veux dire la machine à pots-de-vin.

Un nouveau programme de combat est en attente d'annonce officielle. Le Canada, l'Italie, le Japon et le Royaume-Uni coopéreront sur un avion de technologie avancée. Voir le graphique ci-joint.

Pendant ce temps, l’ARC attend son premier chasseur furtif CF-35A plus tard cette année. Les premiers CF-35A seront utilisés pour l’entraînement aux États-Unis, avec des livraisons à la BFC Cold Lake (Alberta) prévues en 2028. Le statut des combattants de l'ARC semble encore très incertain : le Canada achètera-t-il 88 CF-35A comme prévu à l'origine? (Ils en ont déjà commandé 30.) L’ARC achètera-t-elle également le SAAB Gripen comme chasseur léger non furtif?

The Korean Air Force (ROKAF) operates a large number of surveillance, reconnaissance and electronic warfare aircraft. This month they have added to the total with an order for two Bombardier Global 6500-based standoff jamming aircraft to be delivered by 2034. They contracted last year for four Global 6500-based airborne early warning and control (AEW&C) aircraft which should be delivered by 2032.

The ROKAF currently operates:
-- Four Boeing 737-based AEW&C (E-7) aircraft. It is not clear whether the smaller G6500-based AEW&C will replace these or supplement them.
-- Four RQ-4B Global Hawk large UAVs. (not pictured)
-- Four Hawker 800-based RC-800SIG signals intelligence (SIGINT) aircraft (not pictured)
-- Four Hawker 800-based RC-800A intelligence/surveillance/reconnaissance aircraft
-- Two Dassault Falcon-based RC-2000B SIGINT aircraft
-- For tactical reconnaissance, pods carried by ROKAF F-16s (not pictured)

Considering the relatively compact geography of Korea, this is an impressive total.

An update on the Boeing P-8 Poseidon:

The P-8 is roughly similar to Boeing's 737-800ERX model, but with numerous modifications to suit its maritime patrol and surveillance mission. Some of the modifications accommodate the needs for low-level missions and more aggressive maneuvering than civil counterparts. The P-8 is also structurally stronger and uses stronger wings from the 737-900. The wings have raked wingtips rather than winglets. Given the extensive electronic equipment of the P-8, the generators on each engine were upgraded from 90 kVA to 180 kVA.

The P-8 crew consists of at least two pilots, -- with a third added for longer-duration missions -- on the flight deck. Back in the cabin are five mission consoles, normally operated in the USN by two Naval Flight Officers and three enlisted aircrewmen. Again, for longer flights relief crew are often added. There are crew rest seats in the rear.

During the development phase, the Navy opted to not include a magnetic anomaly detector, which is effective only at low altitude. The initial export customer, India, decided to include MAD in their aircraft, which also have other Indian Navy-specific differences. Other export customers no doubt have specified unique equipment to meet their needs.

Thye P-8 has 5 hardpoints in the smallish bomb bay just aft of the wing and 6 external hardpoints. Typical weapons include ASW torpedoes and the related HAAWC, a guided glide vehicle which can be launched from altitude and carries a homing torpedo down to low level. External weapons can include Harpoon antiship cruise missiles, mines, depth charges and a variety of other weapons. The P-8A generally would not operate in a high-threat environment but is equipped with various self-protection electronic warfare systems.

U.S. Navy:
The USN has 12 operational patrol squadrons (VPs) that deploy worldwide. Each squadron is assigned 6 P-8As and 12 crews. The force is evenly split between the U.S. east and west coasts, with 6 VPs homeported at NAS Jacksonville, Florida and 6 homeported at NAS Whidbey Island, Washington. There is also a single training unit, VP-30, at Jacksonville. There are also two Naval Reserve squadrons flying the P-8A. Other P-8As are assigned to test duties. The total number delivered to the USN is 138. The current budget submission proposes restarting production with a buy of 12 additional aircraft. These may be meant as attrition aircraft as the P-8 is likely to be in service for many years. To my knowledge, only one aircraft has been lost to date -- a P-8A landing at Kaneohe Bay, Hawaii, ran off the end of the runway into the sea and has been written off.

Indian Navy:
India was the first export customer for the P-8. As mentioned above, there were a number of differences that resulted in the Indian version being designated P-8I. After buying 12 aircraft, India decided to augment the force was another 6 P-8Is. The timing was unfortunate, though, with 2025 price increases. I believe that India has decided to go through with the buy. Given the world economic situation, I wouldn't want to bet on it.

Australia:
The Royal Australian Air Force selected the P-8A in 2007 and actually placed an order in 2012. The RAAF operates 14 P-8As, with the final aircraft delivered in 2026.

United Kingdom:
The RAF took delivery of its first Poseidon MRA Mk 1 in 2019. 9 aircraft are operated by two squadrons from RAF Lossiemouth.

Norway:
Norway ordered 5 P-8As in 2017 with deliveries complete by 2023.

New Zealand:
The RNZAF ordered 4 P-8As in 2019. and these aircraft were delivered in 2022-23.

Korea:
The ROKN also ordered P-8As in 2019. The aircraft were delivered in 2024.

Germany:
Germany initially ordered 5 P-8As in 2021 and then added 3 more in 2023.

Canada:
Canada's existing force of CP-140s is tired. Several years of studies and proposals culminated in an order for "up to 16" CP-8As in 2023. Delivery of the first aircraft has slipped from this year to 2027. Given cost increases, the ultimate number of aircraft might be reduced from 16. The plan is to station aircraft in both Nova Scotia and British Columbia.

Singapore:
The latest customer is Singapore, though no details as to the number of P-8s involved have yet been released.

No more Recaro's such a shame.

Norwegian firm Kongsberg, in cooperation with American firm Raytheon, has come up with an excellent multi-role stealthy cruise missile that is being adopted by a number of NATO and other countries. Dubbed the Joint Strike Missile (JSM) (U.S. designation AGM-184A Kraken), it appears to me that it will replace the long-serving Harpoon cruise missile. Like, the Harpoon, it can also be fired from ships or mobile launchers on shore for coastal defense (with a rocket booster.) In the rocket-boosted configuration, it is called the Naval Strike Missile.

As you might expect given the decades since the Harpoon was developed, the JSM has many improvements. Here are some specs:
Length 4.0 m (13 ft 1 in) -- it fits in the weapons bay of an F-35A, thereby preserving stealth until firing
Weight 416 kg (917 lbs)
Speed Mach 0.9
Range 555 km (300 nm) optimal range with high-altitude cruise; 350 km+ (190 nm+) at low altitude
Warhead 120 kg (260 lb) blast-fragmentation
Guidance by GPS, inertial nav, terrain-following, radar-homing or imaging infrared. Two-way data link capability.

The JSM can be carried internally (1-2 missiles) in the F-35A or F-35C (The F-35B's weapons bay is smaller and cannot accommodate the missile). It can also be carried externally by the F-35 (up to 4 missiles), F-15E, F-16 and F-18E/F.

The initial live firing of the JSM took place in 2015 and serial production began in 2021.

Users:
-- Norway: (home fo the main production facility) The JSM became operational on Norway's F-35As in 2025
-- Australia: (construction of a production facility is underway)
-- USA: (construction of a production facility has begun) Missiles were ordered beginning in 2025
-- Japan: Deliveries have begun, but the JSM is not yet operational
-- Belgium: Purchases were announced in 2025
-- Germany: Purchases were announced in 2025 with initial deliveries expected by 2027
-- Canada: Canada placed a C$800 million order earlier this month

There are several other potential users: Finland and Italy have shown interest. Given the perfect fit with the F-35A, I would predict that other F-35 operators would show interest in the JSM.

L'épave du vol Pan-Am 525A, qui s'était amerris le 11 avril 1952, vient d'être retrouvée à environ 610 mètres de profondeur au large de Porto Rico.

Le Douglas DC-4 (C-54 pour l'armée américaine) a marqué un tournant majeur dans le transport aérien des années 1940 grâce à son autonomie permettant de traverser continents et océans. Si les moteurs à pistons refroidis par air de l'époque étaient techniquement pointus, la turbine à gaz s'est avérée bien plus fiable au fil des décennies. Aujourd'hui, les quadrimoteurs disparaissent au profit des biréacteurs, plus économiques et puissants, qui dominent l'aviation civile. L'idée d'un gros biréacteur comme le Boeing 777 aurait été inconcevable à l'époque ; pourtant, nous prenons aujourd'hui banalement des billets pour des vols intercontinentaux sur des appareils bimoteurs sans nous soucier de la fiabilité des moteurs.

Quand je pense au cas d'école des cauchemars de fiabilité des moteurs à pistons, je pense tout de suite au Martin SP-5B Marlin, l'hydravion de patrouille utilisé par les marines américaine et française. Le P5M (son ancienne désignation) a effectué son premier vol en 1951 et est resté en service jusqu'en 1966. Il était propulsé par deux moteurs Wright R-3350. Le souci, c'est qu'en cas de panne d'un moteur, l'avion était incapable de maintenir son altitude avec le seul R-3350 restant.

En 1965, un techrep de chez Martin a acheté ma nouvelle Honda 65cc au Japon pour me l'apporter aux Philippines. C'était génial, mais il y avait un hic : en cas de panne moteur pendant le vol retour, ma moto (déjà payée) et pas mal d'autres affaires auraient été jetées par-dessus bord pour alléger l'appareil et tenir le plus longtemps possible, le temps que le SP-5B trouve un coin pour se poser dans les Ryukyu, à Taïwan ou dans le nord des Philippines. Heureusement, le vol s'est déroulé sans accroc et j'ai bien récupéré ma bécane.

Honda ne faisait que des petites bécanes à l'âge de pierre. Je parie que Llarry s'est payé une S65 Sports Cub de 1965 (à ne pas confondre avec un Piper Cub) :

1965 Honda S65. A mighty 65cc single. The other issue with getting a bike through the techrep was that you had no choice as to make or model. You gave him a couple of hundred dollars and he promised to look around and find you something up in Japan. I was 17 years old and didn't have much money to underwrite the whole effort. I was hoping for a Honda Super 90 -- that was about the apex of what we high school boys could hope for. A couple of the guys ended up with two-strokes and we ribbed them mercilessly. The techrep's son had a Honda CB77 (305cc twin) -- he was the exception and that was probably the largest bike on the base. I might add that the high schoolers with motorcycles had a restriction on their on-base registration -- the bikes could only be driven on base. The base was basically an 8,000-foot runway and no wider than perhaps 1,500 feet.

Mine was red. Otherwise Vreihen16's photo is spot on.

Edit: There was considerable heartburn among the high school girls that they couldn't have bikes. It was just a light murmur at the time but in the years since at high school reunions it kept coming up. All I can say is that 1965 was a very different era. (Also, I did teach my year-younger sister to ride the S65.)

Wait a minute... I seem to remember that you scolded me some years ago when I called a CL-215? CL-415? A Canadair, did you not? And told me that the airplane was now a Viking. Or perhaps I had a dream about firefighting aircraft last night...

If there is one thing I've learned on this board, it is that it does not pay to cross the Nurse.

I don't remember scolding although I am known to do it if required. The aircraft pictured, pre-dates the following info:

" The CL-415 water bomber is no longer manufactured in its original form, as production ended in 2015. The manufacturing rights, type certificates, and support program were acquired by Viking Air in 2016.
Today, Viking's parent company, De Havilland Aircraft of Canada, manufactures a modernized successor to the CL-415 known as the De Havilland Canadair 515 (DHC-515). Production on these new aircraft takes place at their facilities in Calgary and Victoria. De Havilland Canada also offers avionics upgrades for the existing global CL-415 fleet. "
