Not trying to be a dick, but it would be nice to have something that flew higher and wasn't as loud. I'm just some random dude on the internet, but it doesn't fit into the two main niches of either a)man packable or b) quiet/high.

It's a hot topic airplane...

16 hour endurance and 50nm range? Surely one of those is wrong right?

Interesting...I interpreted the 50 mile range as a surface-to-sensor range. If I am wrong that is a pretty sorry drone.

You mean ground control station? A TPOD with an effective 50nm range seems a little absurd, but I don't have that gucci shit on my bird so that's an educated guess.

Your guess is as good as mine...the article notes "16 hours endurance and 50 miles range."

I'm going to guess that the range is the distance it can fly from the ground control station and is probably driven by LOS/altitude limitations on the link.

The RQ-7 is pretty loud (really loud)- the -21 is much much quieter. From 3k feet it doesn't have a very noticable audible signature from the ground.

ah, well... It depends. We recently flew one longer than 16 hours on less than a full bag of gas. The big issue is that we don't have a fuel level indicator. We tell it how much fuel is loaded and it has a fairly conservative fuel algorithm based on engine RPMs. Honestly the algorithm is way too conservative, but you still honor the low fuel indication when you get it, just like any other airplane.

And the 50 miles is accurate, if a little conservative- though not by too much.


I get it guys, so does the rest of the Marine Corps- but we've got what we've got, and we don't have $ for anything else- unless we start to cut F-35s (which ain't happening). At least we did not turn a low observable autonomous, carrier cable strike platform into a tanker...

If we can find a niche for this platform we're in a good place. The nice thing about this one is that the J/CFACC doesn't own this one.

These guys are on the ground, very close to the FLOT, doing face to face briefs with the guys they are supporting, and the supported units can't get enough of it. They are 1/2 way through their deployment and already over their flight hour allotment for the entire deployment.

Yes. Though the upper limit is 20,000 ft. The lower limit is LOS.

Don't feel bad, the Commandant already told them he didn't want it because it wasn't a quad copter...

I don't doubt that it's doing good work, I was just trying to wrap my head around the range. Even if its cruise speed is something ridiculously slow like 10kts, it should be able to go farther than 50nm in 16 hours, unless that range is line of sight to the operator.

Yeah, it's range is limited by line of sight. We've been told that BLOS capability is in the works, and we should start to see it next year. I'm not holding my breath.
