RB04 does less damage than RB15. Is that correct?

[hideki2]

Rb 04 despite having a bigger warhead than RB 15 fails to sink Russian frigate every time. Rb 15 on the other hand is very effective.

 

Attempt #1

Explosion of one of the missiles wipes out the other due to not enough spacing in launch.

Attempt #2

Two Rb 04 launched about 10 sec or so from each other.

Attempt #3

Two Rb 15 eliminate the target.

 

Here is a video demonstration:

I'm thinking, in your video the Rb04s runs out of fuel before hitting the ship.

Could that be part of the issue?

That they are fired slightly out of range?

they run out of fuel when you launch them at maximum range

 

but indeed, looks special...

I'm wondering if you can even expect a single missile to sink a ship. Cripple, certainly. Anyone know what the real statistics are? 1 hit kill probability?

I was able to kill cargo ships with one rb-04 so it depends on the ship

[lemoen]

I meant IRL. Dcs cargo ships go down easily. 30mm can sink them.

Some foggy memory is telling me that the rb 04 and rb 15F have the same warhead, but I may be (likely are) entirely wrong on that and please post a source on warhead weights or something if you have one

That depends on the ship and how good the damage control party is. Against something like a WW2 destroyer, absolutely, single hit kill by ways of breaking the keel is quite likely. Against something bigger and more modern? Much more unlikely, if you don't get that massive structural damage you may or may not get a (temporary) mission kill but most likely not a sinking.

YES RBS15 has 0 problem with that.

 

ATM its really a problem that series launch makes the missiles blow up each other. IRL that would be no problem for the rbs15 since delayed action fuze and for the RB04 neither since its an downwardfacing shaped charge.

my solution is simply fire never in series mode, unless multi target

I will test that tomorrow, but I don't think that's the case. I tried launching them waaay out of range and they seem to glide and track for ever. That time it hit the target while carrying only 500km/h of speed.

[kunterbunt]

I can confirm that Rb15 are way more powerful than Rb04. I'm never able to sink the Neustrashimi with the Rb04 although both missiles hit the target and explode.

With 2 Rb15s, I was able to sink it instantly. I'm not sure, but one might have been also enough, as the ship caught fire.

[kunterbunt]

Wiki article claims that the

 

RB-04 has a 300 kg (660 lb) HE blast and pre-fragmented warhead.

https://en.wikipedia.org/wiki/RB_04

 

RB-15 has a 200 kg HE blast and pre-fragmented warhead.

https://en.wikipedia.org/wiki/RBS-15

 

This does not match the manual.

Theoretically the RB-04 should have more impact on a ship that the RB-15.

[microvax]

Difference here mainly is RBS15 penetrated the target and explodes inside.

 

RB04 is downward focussed shaped charge, since at the time of designing the rb04 sidearmor still was a thing.

 

 

So dunno, makes sense to me that 200kg of 1990s warhead inside a ship deal bigger damage then 1960/70s 300kg warhead exploding over a ship.

 

Even with the same weight class I would expect a 1990s warhead to do more damage then a 60s/70s one.

As the two previous posters have noted, shot placement is the key issue here. It's comparable to hunting big game; a small caliber lung/heart shot can be (and usually is) more effective than a large caliber gut shot.

[mattebubben]

I still feel like the RB 04E is a bit to weak if it cant reliably destroy or atleast cripple Frigates with a single hit...

 

In irl terms if it would not outright sink the target it would for certain put it out of action for a long time (with massive damage).

 

So ingame term since disabling a ship does not really matter i feel like if you hit a target it should either Sink instantly or take enough damage to slowly sink (Burn untill it sinks).

(Since a Crippled ship would most likely be out of the war either way so in a shorter war it would be as good as a destroyed ship)

 

Against larger ships then Frigates then sure 2 missiles or more.

 

But for something like a Krivak having a single Hit do minimal damage i feel like is not realistic.

(Since as already mentioned even if the ship did not sink outright it would most likely cease to be combat worthy for some time)

 

And the RB 04E feels like its underpreforming in general as ive had many instances where i hit Cargo ships with it and they dont die.

 

They take damage and burn for a little bit but they never sink.

And i doubt a Cargo ship would easily shrug of a direct hit from a RB 04...

Testing in impulse mode with a script to show a units health the RB-4 and RB-15 do the exact same amount of damage against a broadside Peter the Great.

Just one attack or did you test mulitiple?

 

As the AVG might be different.

 

The RB 04E feels less consistent in its damage output.

[Grimes]

Multiple times, the results have been pretty much the same. Need to test it at other angles, but that doesn't always impact the damage done to ships.

[microvax]

Something I noticed testing against the grisha, with the RB04 the damage texture is as it is afaik supposed to.

 

With the RBS15 the damage texture sits right at the waterline.

I guess DCS ship damage model simply isnt up to the task of representing the different effects to be expected.

yes. Look alt flight and line atack ASM deck level ship. 10m.

Albatros

GT.Height = 15.8;

GT.Length = 70;

GT.DeckLevel = 3.3;

[hideki2]

I did some more research at different angles and distances, and most of the time they just dont hit the target. In my video, on both attempts the rocket didn't touch the ship, hence white puff. When they hit properly you get a fireball. Anyway I have one hit about 1/3 of the times, and had two hit and ship sunk only once so far.

 

Ps. I also tried messing with QNH to make them fly at a different alt, but it has no influence.
