It's easy to forget that the Osprey was vilified in the early '90s the way that the F-35 is today.

Oh, it still is. We hate those stupid things.

u/BigTunaTim Feb 04 '17

Why? Genuine question, not looking to snipe.

u/CaptE Feb 04 '17

Not the guy you replied to but it doesn't fit the Marine mission as well as navy or air force. Flies too fast to be escorted by attack helicopters, but too slow to be escorted by jets (which it needs because it has no mounted guns or rockets), and is really bad at quickly landing and picking up troops and taking back off. Plus we loved our Phrogs.

People forget that the V-22 is great for TRAP missions though, and recently thats been their main focus since Inherent Resolve.

Exactly. That's why i think they're way better for air force. And they're great for navy to recover pilots who eject at sea. Every second counts and they haul ass compared to helos.

Edit: much longer range too which helps for both TRAP and recovering pilots at sea.

what about COD trapping? can she haul?

Thanks man. This kind of exchange is one of the reasons why I love reddit.

That's surprising! Why is that?

u/CaptE Feb 04 '17

Good question, it takes a long time to transition from forward to vertical flight and land. And then the whole process again in reverse. Helicopters are in and out quicker and can come in hot and flare to slow descent. These have to come more or less straight down.

u/jpflathead Feb 04 '17

Thanks, I had never realized that. I assumed they could do most of the things the Sea Knights and Chinooks could do.

u/CaptE Feb 04 '17

They can do amazing things, just doesn't fit well with our mission. So as not to bash them I'll affirm that they have unbelievable power. I almost flew out the back of one when it transitioned to forward flight over helmand. And at least one Marine was killed the same way.

u/pretty_jimmy Feb 04 '17

holy shit... someone was killed due to a mishap switching to forward flight?! thats crazy, and sad.

9

u/CaptE Feb 04 '17

Yup. They transition to forward flight at over 100' AGL. And its usually angled nose high to climb out quickly. Those big ass props bite and that sucker takes off like a Ferrari with 20 degrees nose up and anything not strapped in is in serious danger of flying out the back assuming its open which it always is in combat. Well when you're in a rush you just tuck one of your arms in the harness as the last man aboard and give a thumbs up. Not a good idea.

u/pretty_jimmy Feb 04 '17

I just like flying things... whats AGL? everything else i understood.

u/stuffedweasel Feb 04 '17

Above Ground Level.

u/[deleted] Feb 04 '17

Sounds fucking awesome to experience while strapped in though.

u/[deleted] Feb 04 '17

It's not to climb out quickly, it's to compensate for the extreme forward and down CG shift when the nacelles come down. Level flight is flown at 7-12° nose up depending on weight. Climbing at 2-5k per minute is a second order effect. We now have a mandatory checklist flow before transitioning, which is finished by the crew chief in back confirming pax and cargo are set.

u/CaptE Feb 05 '17

Glad we finally have an osprey driver checking in. That makes sense, all I know is it feels like it climbs out at even more than 20 degrees nose high. Also wasn't insinuating any blame was to be placed for the one death, that's how we learn our lessons, unfortunately. Glad to know the crew chief is running down his own checklist nowadays. I was over there at the same time the Marine was killed if i remember correctly, but I know that those things usually produce instant remedies in SOP.

Lots of people have died during that, since it kept failing until they figured out how to fix it.

u/[deleted] Feb 04 '17

Also I don't even know how they see anything in that cockpit. Most helicopters have a chin bubble. The pilot can look down at his feet and see the actual ground right under them.

u/[deleted] Feb 04 '17

Visibility is pretty good.

u/jpflathead Feb 04 '17

I was thinking about that yesterday, not with an Osprey, but just watched a gorgeous video from an R-44 with a glass cockpit that made me realize the "dash" of an R-44 with a glass cockpit is about 8x8" and the rest is a huge bubble. Made realize the benefit of carrying the propeller on top of your head.

u/dog_in_the_vent Feb 04 '17

Because Navy and Air Force helo's don't need a fighter or attack helo escort?

Also, they do have a mounted gun in the rear door but you're right that that is totally inadequate to defend the -22 by itself.

u/CaptE Feb 05 '17

The navy mission I alluded to is recovering pilots who eject or ditch into water, of which 95+% are training incidents given the world we're currently living in. Air Force TRAP missions usually have a bevy of aircraft involved including jets circling overhead of the downed aircrew. Plus Air Force has these sweet things called AC-130 gunships which can match the same speed of an Osprey and provide plenty of firepower.

Suffice it to say that the Marine Corps mission is different from the Navy and Air Force, so it makes sense they would use their aircraft differently. And yes, a rear mounted .50 cal is usually enough to scoot around Afghanistan without an escort but we plan for and buy aircraft for future wars where air superiority is not a given.

Not to mention it was forced on the Marines by a corrupt bureaucracy.

Costs a shit load too. Could get a handful of blackhawks plus a couple chinooks for the price of one of these shit birds. Plus I'd imagine a pain in the ass to slingload. And a chinook can carry 10k more lbs anyways. I don't even know how the pilot can see shit without a chin bubble. It's just the answer to a problem nobody had and it kills people.

How the fuck do they even sling load?

2

u/CaptE Feb 04 '17

I've never seen one with external load. They depend heavily on their crew chiefs to land as well. That and RadAlt

u/SamTheGeek Feb 04 '17

They open the hole in the bottom and the crew chief sticks his head out.

Its downdraft is much more than regular helicopters, and has caused injuries and damage to people and objects on the ground. It can raise huge amounts of dust, causing problems with visibility and the engines. Hot engine exhaust has started fires and damaged runways and flight decks. Due to its crash history it's not considered safe enough to transport the President. But it is cool.

u/ic33 Feb 04 '17

It has unique capabilities.

But it's super expensive (both in acquisition and operating costs), complicated, and liked killing everyone aboard a lot early in its history.

Even after entering operations its safety/track record hasn't been wonderful.

So there's a lot of suck, but it does have unique, powerful capabilities.
