Shooting air target with gun

Mau · 02-09-07, 09:19 PM

Hi all,

A little bit earlier (think last week) I heard that people tried to shoot their own helicopter to see if the 76mm can shoot air target. I think the results were negative.
Did anybody tried with an air target other than their own helicopter.
Ever been successful?
Now if that doesn't work, hopefully that can be fix, because that gun (even though not that effective) is suposed to shoot air target.

Thanks

If you don't like the helo pilots you can allways resort to using the ciws.
Its quite effective. :rotfl:

Manual guns are much more fun. Did you know you can actually kill whales with those ?

You can kill whales without spending ammo, just use the sonar bulge in front of a frigate

And I thought that NAVY is concerned with biologics....

Damn, I hate being right!!
Anyway, from which movie is your sig?

Looney11 · 02-12-07, 04:05 PM

Well, we're watching out for our little and bigger biological friends...

But as I found out that day, when the bulge of a whale appears 30 feet in front of a ship doing 15 knots, there's nothing you can do, even hard rudder to starboard wasn't enough to steer clear.. one loud BAM and one cracked polyester dome.. (hole roughly 6 feet in diameter).

When we got back to port, the hole had grown to almost 30 feet, transducers were broken by the salt water, we had to pump water out of the room abow the sonar dome continiously as the hatch was not sealing properly.. all in all, the sonar took a hit so to speak..

Never saw the whale again, we even did a 180.. nothing.. poor sod..

I read it somewhere that active sonar confuses their orientation and they end up on beaches....

Looney11 · 02-12-07, 04:13 PM

yeah, it's sad.

Halifax harbour has a designated sonar unit to keep whales from entering the harbour I heard. From my old shipmates I heard tales of horror trying to sleep onboard when the frigate a jetty away goes PING>>>>>..... <<<<<<<.......

Worse are some "advanced" sonars.. Ping..BRIEIREUEUEEEe....

I'm glad I never went through that experience

Poor creatures... Should't they stick to passive only, as active gives away position?

my sig ?
its not from a movie
but from the "Chapelle's Show"

Ok now back to the topic I started.....

So I guess nobody tried to shoot an air target with gun (76MM) other than own helicopter.
If I have time then I will try to make a scenario with a slow mover coming on top of a frigate and try to shoot at it.

I tested it now .. it seems that 76mm does not take ballistic trajectory into account. And then it does not take projectile speed into account. That's why it can't hit.

CIWS seems to shoot in straight line, not parabola. It also has much much faster bullets. That's why it can hit. It's just my theory at the moment, I'm doing more tests.

Edit: I did some more test .. CIWS shoots nice ballistic curve .. and it leads the shot nicely .. so it just hits. I just can see the difference in the database.
