Why The Galley And Toilet On Su-34?

From the Wikipedia article, it says the Su-34 has a combat radius of 680 miles and a ferry range of 2000+. However, it states that it is designed for "long missions" hence the galley and toilet ammenities, but how would a 1300-mile roundtrip to target be considered "long"? These ammenities would make sense to me on an intercontinental range bomber, but with a combat radius of less than 700 miles, a theoretical mission would only be about, what, 3 hours? Or do they have some grand plan to use in-flight refueling on long-range strike missions?

On internal fuel and perhaps following some “ground hugging” attack flight profiles (the Su-32/34 has a terrain following radar). The number doubles if you use some drop tanks.

Ah, that does make more sense now since low-level flying does murder fuel efficiency. I was just assuming that combat radius was at altitude, but obviously they may have calculated at low-level.

The Su-34 is air refuelable. It would need to be because it carries external stores.

So, after using the toliet andd it is flushed, is the blue water stored in that long tail boom, or is the just the bunk they rest in?

The toilet was placed in there forr pilot comfort their meaning for long missions is not range they are meaning loitering time, the SU-34 was also designed for intelligence gathering and photo recon not just bombing the 1300 mile round trip may last for 16 hours try holding it yourself for that long under normal conditions and see how easy it is, thats why they felt the need to add those things, US Bombers have the same features and can loiter for hours over a combat zone, also the Su-34 has in flight re-fueling. They did note that they have paid some attention to US tactics over the years.

I completely agree -- I was just originally thinking of a normal strike mission -- to target and back. Once you introduce loitering then it makes a lot of sense since as you mentioned those can be long flights. I'm all for bombers having these ammenities.

I heard in the eighties the Rrussian did a trail with a tandem seat Flanker flying a mission from an airpartport around Moscow to a target in the east, asian part of Russia. The flight had a few in flight refuellings and retruned home sucessfully after a flight. The crew was grey, dirty and exhausted however, with specialists doubting their combat effectiveness. That made them start looking for a side by side configurations with room to stretch, go to a lavatory and have good meals.

A rear-facing radar is in that long tail boom to track targets and guide the rearward firing R-73 missile. Chasing an aircraft ain't what it used to be I guess. I hope they'll not export them.

Oh, I don't know.....sounds to me like the used blue juice would make just as an effective weapon if released.  Wink

Ah, but you wouldn't want the conflict to escalate to chemical warfare!!  Wow!

Much cleaner to take out a chasing plane with an R-73 than a bucket of sh*t Big grin

Considering that all flankers flown by the "Soviet Union" had no air to air refuelling capability I find that somewhat hard to believe....

I found these of the Su-34 in a random forum when looking for walk-around pictures awhile back. You have to dig around somewhat for cockpit interiors. Scale modelling websites usually are a good resource. The larger pictures can be enlarged by clicking on the thumbnail and then on the image itself.











These are obviously not a direct photo of the toilet unit itself, but these do give a good idea of the space behind the seats - pressure bulkhead, boarding ladder/access hatch, avionics racks, and the space inside that one could stretch out with the ladder/hatch closed. From what I understand the toilet is placed between the seats. It could possibly be just a portable unit like one would use for camping as it's probably unlikely you'd want to include the added weight of a plumbed system with storage tanks.

I also remember having some very detailed cockpit interior pictures of the B-1B of the galley/lavatory unit, front seat cockpit, and button/label readable rearseat offensive and defensive armament panels.
