OP: As always, feedback, suggestions wanted and appreciated.
New thread this week - apologies, once again, for the hiatus, as I expected the thread to last over the weekend, although I’m beginning to suspect that they have a strong tendency not to. The Marksman has been an AA system I have not covered even tangentially, and I thought it would be interesting to have a look at a system that was not a vehicle per se, but a self-contained AA suite marketed independently of vehicular accoutrements. It is perhaps a shame, that Marconi, with its reputation for quality and reliability in its radars, was unable to secure lasting export deals beyond Finland. Like the Otomatic, the Marksman was yet another nascent SPAAG design that did not see success in spite of its positive features. Considering Finland’s remarks on the effectiveness of the Marksman and their continued usage in the present even with more modern options available, it is a great shame that the G6 Marksman conversion deal between Marconi and Denel in 1994 did not go through.
Stats are for the Leopard 2 mounted Finnish variant.
Here’s an early Marconi brochure for the Marksman: (Album is private, so links are for individual pages)

More tank news, as per the new format.
If you have more queries regarding a news story, just point it out, and I’ll further elaborate and provide links.

In our first piece of post-election defense news, it appears that until March 2017, the Pentagon will be functioning on a stopgap Continuing Resolution budget until the transition to President-Elect Donald Trump’s administration is complete. With Mr Trump’s anti-sequestration attitude, it may be the case that there will be a marked increase in Department of Defense budgets in the near future.

Serbia is currently in talks with Russia to procure six MiG-29 aircraft and with it an undisclosed number of AFVs of miscellaneous type. As a prelude to this, Russia in the past had offered to sell Belgrade Buk SAMs, although budgetary constraints had scuttled the deal.

The field has narrowed for the British Challenger 2 Life Extension Programme, with only BAE Systems, GDLS and Rheinmetall being downselected in the Assessment Phase of the competition. The contract for the LEP is due to be awarded in December 2016, covering a maximum of 227 Challenger 2 MBTs, a figure liable for downwards revision due to restructuring. At the end of the Assessment Phase, one contractor will also be selected to be the Design Authority on Challenger 2s until the end of their service in 2035.

The Russian Ministry of Defense is reportedly planning to upgrade a number of T-80BV MBTs in military storage and bring them into service. Spearheaded by Omnsktransmash and SKBTM, the new tanks will feature the Sosna-U FCS and improved ERA, as well has receiving climatic suitability for the conditions of the Arctic, Siberia and the Far East.

The Republic of Korea has test fired a new upgraded K30 Biho SPAAG sporting four KP-SAM Shin-Gung MANPADS this week. Manufactured by LIG Nex1, the upgrade adds a much needed guided missile capability to the electro-optical gun based 30 mm Biho system.

And that’s all for now.

Germany should've continue gun tanks.

Technically speaking how effective is an electro-optical gun against modern close range aerial threats like planes, choppers and most importanty, PGMs?

This contraption came out of Iran a few years ago, they strapped 4 Zsu 23 mm autocannons together and equipped it with EO guidance. How effective would it be with good fire control against PGMs?

Why not T-80U's or are they trying to bring more older vehicle up to higher standards since the T-80U is already more "modern" then T-80BV's that it can stand on its own legs better then the T-80BV?

Fuck, I want to build a tank of some kind, even if it's totally not road legal or anything.

Where the hell can I find out about how tanks actually work? I'm happy with engines and gearboxes, but the steering mechanisms they use are pretty damn complex and I can never find how they function.

>>32038031
If the end result is the same why not upgrade the tanks that are less capable in their current form.

>>32041474
Here's a question I've had for awhile, how do the stop the ammo from firing when it gets hit? How come there's not a bunch of APFSDS and HEAT slaughtering the crew when the turret bustle is hit?

>>32041617
>how do the stop the ammo from firing when it gets hit?

You mean what keeps it from shooting from the ammo rack into the crew compartment like it was fired from the gun?

The answer is: Because it's in the ammo rack, and not in the gun. You need the gun to build up the necessary pressure in the right place to squirt the shell any distance at all. If you just set off a round all by itself, it'll just blow up in place.

The case for these rounds is basically just a paper tube with some goop in it to keep it weatherproof. They're not very strong.

>>32041668
HEAT could still go off though

>>32041617

It's not the shell that fucks shit up, it's the propellant. Wet stowage was the answer to that question.

>>32041689

I can't find anything specific about it, but I seriously doubt that the HEAT warheads can go off just from being on fire. Most modern munitions are fireproof in that way, and have been for a really long time (the past 50 years at least).

I read a book about Chechen war where the conscripts were sticking artillery shells in their camp fire to melt the plastic explosive out, so they could collect it and see who could get the largest collection

so yeah, fire probably wont do it

>>32041474
That...is actually a really clever idea.

>>32041668
>You need the gun to build up the necessary pressure in the right place to squirt the shell any distance at all. If you just set off a round all by itself, it'll just blow up in place.

Ok thanks I never knew, I thought a bullet would still fly off and hit something if you accidently hit the primer on it but now I know better

>>32041751
Similar stories of plastic explosive used in Vietnam as campfire fuel.

>>32041719
Nowadays, inert, separated propellant charges are usually the answer to that issue.

>>32042201

This is about small arms ammunition, but it gives you a good idea of what happens to ammunition that catches fire.

>>32037929
Production will be underway by 2017 iirc.

>>32041593
I'm talking more about the double differential shit or whatever it is that allowed American tanks to use steering wheels.

>>32038896
>Where the hell can I find out about how tanks actually work?

you're not trying very hard. There are a couple books on the stug III in your pic.

The thing is, not all tanks work the same. Some use something simple like applying a brake, others might use special gearing. Some even have an engine per side.

>>32042687

Ya, usually.

Here is what happens when a tank brews up:

Insensitive propellant isn't really a thing yet, at least on the level of explosives.

>>32043023
>Some even have an engine per side.
One thing that comes to mind is the Strv 103 which has two different engines.

I hope I don't regret this, but here is a bit of the steering set up for the stug/pz III.

This is a from an original manual I own. I'm in the process of scanning and cleaning it up so it can be reprinted it.

If anyone wants to buy a copy later, email me at [email protected]

It will probably be 15 to 25 per copy.

What's even better is something like the Objekt-640's turret bustle ammo rack- Its designed to be easily changed with a full load of ammo much like a rifle magazine with a small loading crane.

So I just found this cool list of stats for WWI tanks:
http://wio.ru/tank/ww1tth.htm

Am I right in assuming that ~10-12mm of armor was enough to stop common German small arms of the day?

What about larger calibers, like .50 BMG, or .55 Boys?

>>32044449
10-12 mm could stop even German SMK rounds most of the time. SMK rounds were AP ball ammunition issued to MG08 gunners for AT use, but they were unreliable pieces of trash a lot of the time.

>>32044449
>What about larger calibers, like .50 BMG, or .55 Boys?
Probably not. If they worked okay against WWII early mediums, then WWI tanks would prove vulnerable.

So this is something I felt the urge to jot down, it seems like it would work well enough for something I could possibly build myself.

The clutch might not even be necessary, it could use a torque converter instead, although that wouldn't be as efficient.
