[WillyI]

Il convertiplano ha avuto uno sviluppo tormentato, le potenzialità del mezzo sono valse la pena?
Personalmente credo di si.

P.S. credo che dobbiate aver fatto il login per vedere i video.

Vi sono diverse versioni del v-22:
Una per opeazioni speciali con una torretta remotizzata armata con una minigun da 7.62 mm montata sul ventre (non riesco a trovare una foto... qualcuno aiuta? )
Un'altra versione interessante è quella equipaggiata per missioni search ad rescue (ricerca e soccorso).

Ho trovato un anticipazione purtroppo non molto chiara, dovrebbe trattarsi del GUA19:






La modifica dovrebbe riguardare sopratutto gli CV-22B del USSOCOM ( U.S. Special Operations Command ) che oltre ad essere meglio armati hanno serbatoi più capienti e un radar per per il volo a bassa quota.

Cmq normalmente i V-22 di serie dovrebbero avere tutti la predisposizione per armi brandeggiabili tradizionali.

E del BA609? Cosa sapete al riguardo?

Sul BA609 c'è un recente articolo su Rivista Italiana Difesa, che mi pareva ben fatto.

Intanto ecco un articolo riguardo le prime esperienze operative dell'Osprey in Afghanistan:

MV-22 and ABV Meet Expectations
Feb 5, 2010
By Paul McLeary
Washington
While CH-53 helicopters were unloading Marines from Kilo Co., 3rd Btn., 4th Marine Regt. in the Now Zad valley in Afghanistan’s Helmand Province during the early morning of Dec. 4, history was being made a short distance away. Two MV-22B Osprey tiltrotor aircraft were disgorging Marines from the reconnaissance unit Task Force Raider in three landing zones at the opposite end of the valley, kicking off an assault on the Now Zad area to eliminate Taliban influence by first driving Taliban insurgents out, then establishing a permanent Marine/Afghan security force there.

Dubbed Operation Cobra’s Anger, it was the first test of International Security Assistance Force commander Gen. Stanley McChrystal’s ambitious plan to conduct a robust population-centric counterinsurgency, which will be bolstered by the 30,000 troops President Barack Obama is sending to the theater. It also marked the first time the controversial V-22 Osprey was used in a major combat action.

But before the 1,000 Marines who eventually took part in the operation could be put in place, the Osprey had to do its part. After the initial drop, during which no shots were fired at the Marines and the 150 Afghan soldiers with them, the tiltrotor continued to participate in the mission by flying general support operations throughout the area. “Just like any other support squadron out here, we’re fulfilling many of the same missions they’re fulfilling. . . . We’re able to fly some of the longer legs, but we’re fulfilling our role as a medium-lift, sole-support squadron,” Lt. Col. Ivan Thomas, executive officer of Marine Medium Tiltrotor Squadron 261 (VMM-261), told DTI in a telephone interview from Camp Leatherneck in Helmand Province.

In November, 10 Ospreys from VMM-261, based at Marine Corps Air Station New River, N.C., deployed to Afghanistan for the first time. Osprey units completed four deployments to Iraq from 2007-09. Cobra’s Anger “was a nice initial start for the V-22s in Afghanistan,” Thomas said. “It was a straightforward mission that was flown under ideal conditions.”

Those familiar with the rocky history of the V-22 know how significant a successful deployment to Afghanistan is for the corps. After more than 25 years of engineering problems and $16.4 billion in development costs, and with the legacy of four major crashes that cost 30 lives, the Osprey has generated its share of doubters—and the aircraft’s $120-million price tag doesn’t endear it to critics. Though the aircraft performed well in Iraq—where it arrived too late to take part in any of the combat the Marines experienced in Al Anbar Province—the Government Accountability Office (GAO) in July 2009 cautioned Congress that the aircraft “has yet to fully demonstrate that it can achieve the original required level of versatility. . . .” The GAO added that “Based on the Iraq experience, the cost per flight hour is more than double the target estimate,” and noted that the Defense Dept. “is therefore faced with the prospect of directing more money to a program, the military utility of which in some areas remains unproven.”

Assessments like that make the deployment to Afghanistan, where it will be in the thick of the fight in volatile Helmand Province, crucial to the program’s future.

So far “they’re handling quite well” in the harsh climate and high altitudes, Thomas said. He concedes that while there may have been “some expectations and concerns” about the aircraft, “very quickly people here saw that we operate just fine, and right now we’ve gotten to the point where we’re just another assault support platform out here—but we’ve got longer legs and can fly faster.”

In general, the Osprey has been plagued with mission-readiness rates hovering at 62%, but operations in Afghanistan have seen those rates rise steadily through the 80% range, Marine Corps Commandant Gen. James Conway told reporters in December. Conway said he would like to see the tiltrotor “climb the ladder to the 90%” range. “It’s on that trajectory,” he remarked, adding that any problems that have arisen so far do not involve the aircraft’s major systems. “This isn’t just a replacement for the CH-46 [Sea Knight helicopter]. . . . We’re using [V-22s] in some of our operations to land troops deep and to very quickly build up troop numbers on deck.”

RIDLEY PARK, Pa. — The V-22 Osprey is getting an extra 20-knots of speed and more than 1000-pounds of lift power without any hardware changes, Boeing officials revealed this week.
Instead, engineers simply updated the tiltrotor’s software, boosting the Osprey’s max cruising speed to 260 knots, according to Bull Sunick, Boeing’s V-22 business development manager. A similar software upgrade will soon tweak propeller angles to give it an additional 1,000-pounds of power when in a hover.
The V-22 is “the iPod, if you will, of rotorcraft in that we were able to improve our [airspeed] to 260 knots through a flight control software upgrade,” Sunick told DT after a tour of Boeing’s V-22 assembly line here (hence the Instagram photo I took). “You go home, you synch your iPod and you get the new software on there — we kinda do the same with the airplane, it’s all ones and zeros…it was through a software drop. A new version came out, kinda like your new iPod software and boom, no new engines no new drivetrain.”
This was just after he’d finished reminding me of how an Air Force Special Operations Command CV-22 had actually performed the tiltrotor’s very first combat search and rescue mission nearly one year before USMC MV-22s rescued the pilot of that F-15E Strike Eagle that crashed in Libya last March.
(Boeing brought a bunch of reporters up to Ridley Park for the 50th anniversary celebration of the CH-47 Chinook’s first flight yesterday, DT was given a tour the nearby Osprey line afterward.)
On June 1, 2010 a helo carrying 32 people went down during a special operations raid near Kunduz in Northeast Afghanistan. A severe dust storm and the Hindu Kush mountain range foiled attempts by other helos to reach the stranded crew and passengers who were under small arms and mortar fire. Two CV-22s from the 8th Special Operations Squadron launched out of Kandahar in southern Afghanistan within two hours of being alerted and flew 400-miles straight to the site — over the 15,000-foot mountains and through “very low visibility” – and back to Kandahar with the 32 stranded troops in less than four hours.
“There was a mountain range in between” the American bases at Bagram and Kandahar “so conventional rotorcraft would have had to snake through the valleys and whatnot,” said Sunick. “V-22 flew over them. The guys went up, they went on oxygen, went over the mountains, went direct as the crow flies and then when they were coming close the weather was extremely bad, I think they had less than a quarter-mile visibility. Now you’ve got your [terrain following radar] sniffing things out for you, giving you a clear picture and so the guys were able to go in there. It was a hot LZ, they were under fire, they landed, picked all they guys up — 32 folks crammed in the back of the airplane — and they got out of Dodge and made it back.”
Now, the V-22 had its share of development problems [nightmares, at times] and it’s still working through problems with fine sand wearing down engine parts faster than engineers would like and it’s mission ready rates when deployed are roughly 70 percent. Still, you can’t argue that the speed and ranges at which the bird flies combined with its VTOL abilities make it invaluable for missions like this.
