Not even close. This ship is absolutely giant.
- qbasic_forever 6y agoHrm change of plans, let's pull a few ICBMs out and set them up on each corner with massive tow lines. We'll get it out the way in an instant... and into low earth orbit minutes later!
- WJW 6y agoYa no. An ICBM like the https://en.wikipedia.org/wiki/SM-65_Atlas https://en.wikipedia.org/wiki/SM-65_Atlas has a launch thrust of only 1,300 kN, or about 130 tons. That would lift about 4 of the 20000 containers aboard.
- lstodd 6y agoForget it. Let's just nuke it, them nuclear weapons have to be disposed of somehow, and the channel needs some expansion, it seems.
- smegger001 6y agowell lets just dig out the old mothballed project plowshare out of the coldwar toolbox and see what we can do. https://en.wikipedia.org/wiki/Project_Plowshare https://en.wikipedia.org/wiki/Project_Plowshare
- pjc50 6y agoIf I've done the maths right, you need a force of two billion Newton to lift it, and even if you round up a https://en.m.wikipedia.org/wiki/LGM-30_Minuteman https://en.m.wikipedia.org/wiki/LGM-30_Minuteman to 1MN you still need two thousand of them. ICBMs are not that big. Use musk's starship and you need >166 of them...
- qbasic_forever 6y agoDrat, we never should have given up on nuclear powered rocket engines in the 50s!

- garaetjjte 6y agoICBMs won't do it, we need something stronger. I cannot find how much ship weights itself, but deadweight tonnage which is about 200000t. Let's assume 300000t. Thrust of Saturn V S-IC stage is 3300t, with diameter of 10m, empty mass of 130t and 2150t of propellant for 150s burn time. It would need nearly 300 fully fuelled S-IC stages to lift it! Which is a bit too much, as with 400x60m ship area we can only fit about 240 stages. But as we're definitely not going into orbit anyway we can reduce propellant amount for shorter burn time. Cutting propellant by half reducing burn time to 75s we only need around 143 stages, fitting on ship with room to spare. So in that regard it is doable. But there's problem of what to do with all the exhaust, as rockets obviously aren't designed for pulling load attached to the bottom...
- qbasic_forever 6y agoWe'll dig down beneath the ship hundreds and hundreds of feet to build the rocket from below, with huge exhaust shafts to let the pressure exit.
- rogerdickey 6y agoWhat about setting off a nuclear bomb underneath the ship?
