Rb 04E: the Viggen's signature weapon

[Cool Breeze]

It blows my mind that they were able to make targeting logic this complex (and fairly compact) without the use of transistors, and in 1961 no less, 16 years after the end of WWII where all of the weapons were dumb. I realise this is an upgraded version but im guessing the original Rb 04 was fairly close to the Rb 04E

While their not even in the same league as the Rb-4 and most weren't used until very late in the war. There were several guided munitions used during WW 2.

 

Most were command guided but there were some autonomous weapons like the ASM-N-2 Bat and the VB-6 Felix.

Thanks for being the RB-4 into its own sub-forum.

When i visited the small Swedish Missile Museum in Arboga i talked to the staff there and they told me the Gyro control unit was actually a direct development of the V1 missile which had been reverse engineered and fine tuned (an extra gyro was added for roll stabilization the V1 could famously be flipped over to make it crash).

Thats badass! Great photos too :thumbup:

Are those valves (vacuum tubes) there in those cans ?

Yes :-)

Analogue control systems theory :-)

 

Some extremely intelligent resources spent lots of time and money on these types of problems.

This is by far one of the most outstanding threads I've seen on this site in a long time, thanks very much Renhanxue for posting that extremely detailed description of the missile & how it works :thumbup:

 

My toughts exactly ... really amazing thread; I discovered it thanks to a link from xxJohnxx's Rb04 video at YouTube

Hi, can I translate this article to Chinese and post it on website? There are plenty Chinese dcs players, but aren't many nice articles due to the language obstacles.

I will certainly mention your credit!

I actually sent him a private message:)

But yeah, it's a good advice.

I responded to the PM all the way back in November but never posted here for some reason, so just to put this out there: if anyone else wants to do this for any language, by all means go ahead! I'm very happy that the writeup is interesting to others. Also, feel free to link to your translations in this thread so people who encounter the English version first can find translations from here too.

I wanted to train the use of that weapon, but every time I launch it, it goes into the water and explodes. Alt 100 meters and in range. Three ship ahead. Any ideas?

Got a short track perhaps?

You are using the RB-04 that are for the AI. You should try again but this time take the RB-04's that are not designated with "(for AI)".

[nazradu]

You are right mate! Thanks for saving my sanity!

Also make sure you set the switches. Don't use GRUPP unless you are completely sure the ships qualify as a group as defined in the manual. Otherwise the missiles will fly right past the ships looking for a group.

Angle jump settings also seem to cause a significant drop in Pk from the missiles. I have 10 ships in a 1+3+3+3 box formation on my range with the main group being within 2.7km both in lateral and trail distance and last me and a buddy fired missiles one hit and the other three ended up doing a wild last minute turn to try and hit their targets but ended up going above and splashing right behind.

 

Unsure if it's just setup errors, if the missiles really need a very cooperative target, or if it's a bug of some kind but it makes using them a bit underwhelming.

A track would be very useful. Or provide the mission file so others can test it themselves. 

[TheSkipjack95]

Trying to reproduce the issue first. Are the angle jump and group settings exclusive btw ? As in I can either target multiple ships in one group XOR target two different groups

[TheSkipjack95]

Rubbish04.trk

So I had a few goes with this setup, changing settings to see if that makes a difference, and it's only ever one missile that tracks and hits.
This track was with right missile angle jump and random target selection within a group.

As you can see launch is within parameters and the left missile has ships well within its cone but it just does not track.

[MBot]

Just a little heads up. It took a couple of years, but now we finally have the Viggen's signature target to go along with its signature weapon

Ropucha class LST:

[SOLIDKREATE]

And hence the entire reason why I bought the Viggen
