Weapon request - GBU-62B(V-1)/B Quickstrike-ER

GBU-62B(V-1)/B Quickstrike-ER

Still have an open request for this one. We've got to do some code work to get the mine + GPS stuff to work. Bear with us!

I have noticed that helos, specifically AH-64s and Pave Low IIIs, nap of the earth flights are always 500ft AGL regardless of day or night operation. Sorry to say i haven't noticed this with other countries aircraft. There are not enough hours in the day to investigate a program so complex. I was using the excellent "Task Force Normandy, 0.95" scenario in this sub-forum.

Is this altitude a function of the database, or the program itself?

A friend of mine, who flew Apaches in Desert Storm and later in Iraq, and I were discussing this, and he stated they operated much lower when there were threats to be avoided. Sometimes as low as 10 feet! I think that might be an extreme case, but 50 feet might be more "normal" for NOE operation for TFR equipped aircraft. There are not any official sources for that. Even so I am curious.

I know there are bigger fish to fry, but thanks for the excellent work and time invested.

Thanks Peter. This is a bit of a research project. Any chance you know what aircraft operate within these parameters?

Unit request

A couple of days ago China conducted another test of their hypersonic glide vehicl
e called DF-ZF (also called WU-14 by western sources): http://www.popularmechanics.com/militar ... on-system/

The easiest way to do it would be to add another DF-21 variant:
SSM Bn (DF-21D [CSS-5 Mod-4) ASBM DZ-FZ Mod)- China, 2022 (hypothetical)

Just increase the reentry speed and make it basically untouchable for terminal BMD missiles (ERAM, THAAD).
SM-3 Blk IIA and GBI should be capable of intercepting it though.

Well, there are 5 issues out there:

1, what does DF-ZF looks like? Without an official pictures out there, even hypnotically added will not be agreed.

2, what is the flight characteristic and guidance of it?

3, is DF-21 a true launching platform? Any other platform/warhead devirates?

4, what is its intended target to be use against with? Land unit? Surface vessel? Airfield?

5, any other functionality, as well as intercept/countermeasure resistant systems in it?



If we can fill out these questions with reasonable answers, then we might think about it.

If we can fill out these questions with reasonable answers, then we might think about it.

1) Its a warhead mounted on a ballistic missile, I don’t think it really matters how it looks like? The database has tons of stuff we don’t know how it looks.
Anyway, aviationweek had a concept picture from a chinese academic paper:
http://aviationweek.com/awin/us-navy-se ... der-threat

2) Probably very similar to the flight profile of the Falcon HTV you can check out online. A rocket boosts the vehicle to near orbit, the vehicle separates, starts engine, enters the upper atmosphere and accelerates to maximum speed while maintaining maneuverability.

Think of it as a faster DF-21D ASBM with a flatter trajectory. You build a guidance package for that one, just copypaste it.

3) There is no reason why they cant mount it on any ballistic missile in their arsenal with a decent throw weight. I suggested the DF-21 since it’s the most logical choice.

4) I never understood the reasoning behind target restrictions. If it can hit a moving surface vessel they can hit stationary land targets as well.

5) Whatever you put on the DF-21D ASBM? I don’t think there is much more information on that one.

Notice the 8-12x and 1996, #2928 is probably the Ka-50N/50Sh

The initial version of the Ka-50 was effectively a day-only / clear weather machine, the intent being to then enhance its night / all weather combat capability, to produce a "Ka-50N" -- "N" for "Nochoy / Night. Work was done from early in the program to evaluate low light level TV (LLTV) and forward-looking infrared (FLIR) imaging systems, but they simply couldn't be made to work right, with social chaos bringing development to a crawl. In the mid-1990s, work was done to evaluate FLIR sensors from Thompson-CSF of France, but that was seen as only an interim step.

By late in the decade, the Urals Optico-Mechanical Plant (UOMZ in the Russian acronym) of Yekaterinburg had developed a series of workable imaging / targeting turrets -- "gyrostabilized optronics systems" or "GOES" in the Russian acronym. From 1997, a Ka-50 was evaluated with a nose-mounted GOES turret designated the "Samshit-50", which featured an LLTV, FLIR, laser rangefinder / target designator, and Vikhr laser guidance system. This demonstrator was eventually fitted with a mast-mounted Phazotron-NIIR Arbalet air defense radar and a full "glass cockpit", with three large color flat-panel displays. A second demonstrator was kitted up, featuring a second, smaller GOES turret for navigation in the nose forward of the targeting turret. The Ka-50N demonstrators with the ball sensor system were also known as "Ka-50Sh", with "Sh" standing for "Shar (Sphere)".

Okay, I promise these are the last ones for a while. Probably. Both are for the Philippine Coast Guard. I figure between India, Japan, and the Philippines, there will be enough coast guard platforms in the database to tell all sorts of anti-smuggling, anti-poaching/fish war, anti-spy ship stories, etc. Thanks for considering these!

Sorry for the delay. I double-checked with my friend. He flew AH-64As in Gulf War I, and Longbow models in Gulf War II. They escorted Pave Low's in II.

He said the 10 ft runs were brief excursions when threats were detected and all were in hard-pan desert terrain. Normal limit for NOE was 50 feet AGL - in the desert easy and a real 50 ft level above the earth. He said in training they operated at 50 ft AGL, but in forest conditions, that meant normal altitude was 50 ft above anything like trees or other natural obstacles. However normal attack runs often dipped below tree level for visual and radar concealment. Hope some of this helps. I don't know of any place where this stuff is written down for general knowledge, except for some book-type memoirs of pilots.

I found another issue for your consideration. Weapon 2597 APKWS Hydra II. In the latest database entry, the manufacturers' data lists the effective range as 8,000m (4.97 miles / 4.3nm) and max range as 10,500m (6.5 miles / 5.6nm) but in the data section, the range is said to be 0.2 - 2 miles. A little short legged.

Thanks for all your hard work.

FLIGHT International article page from 6 Nov 1975
https://www.flightglobal.com/FlightPDFA ... 202439.PDF

This one-pager describes the 1975-era purchase of Euromissile HOT-armed Gazelles by the French Army, and similarly-armed BO105s by the German Army. HOT-armed helicopters are described as "popping up out of ground cover to fire their missiles while remaining partially hidden." These platforms are more appropriate for CWDB, but the implication is that most helicopters should be able to carry out combat operations at very low level in the day, and at night if NVDs are in use.

Just me...but that would seem like a whole lot of work for an overall minor issue. Maybe just changing the 500ft minimum flight level to 100ft would suffice. That alone would change the radio horizon from 32 statute miles to 14 (assuming 0 ft elevation for the radar antenna), about a 50% decrease in vulnerability. 50ft would change it to 10 miles. That's a significant change from 32. And it wouldn't take but a minute to re-code.

I didn't want to make a giant programming issue of it. If the minimum altitude thing is a database issue, it would be even more work. You guys know what is possible and practical.

[skjold89]

I am wondering if its possible to slightly increase the capability of the #1140 Bofors 57 mm Mk 3 and the #1311 Mk 110 57 mm to shoot down incoming missiles? It has a PH of 1 % against sea skimming missile despite its manufacturer advertising its ability against anti-ship missiles. Don't get me wrong i don't expect it to be a wonder weapon but feels a bit off. Base PH is 25 % and with sea skimmer modifier -30 % and target size modifier -9 % it basicly has zero chance to actually hit. (test against Kh-35U/AS-20 Kayak)
