Yup, and it can launch nukes over 300m from cloud level to sea level. Sure, it's not as accurate as ICBM, but not everyone uses that mod. the great thing is once you have it built all you have to do is replace the tnt and the nuke before you fire it again, no need to replace anything if you build it properly. Also, due to it actually launching the nuke away from you, the only ones getting radiation will be those at the target area.
Edit: I just messed with it a little more and added a longer-range barrel extension and support for nuke clusters. Basically, I increased the range by about 50m by added a barrel and made it so you can launch 7 nukes instead of 1 at a time.
