Is this a number you trust? It is like the range of AAMs on wikipedia. Not only is this number unreliable, if the US is gearing for a 1st strike (and indications are exactly that), you can bet that inventory will be increased significantly and without making a public show of it. Also, it won't just be Tomahawks in the 1st strike packages. There will be BMs, drone swarms, and (most likely) additional threats that are not yet declassified.
The missile purchase numbers is available for all to see. These things cost a lot of money to develop and then produce.
What ballistic missiles program are you thinking of? US hasn't had one since Pershings for obvious reasons. Are you saying they should do it just because PLA is doing it? where would you launch it from? How many ground launchers can you have in the region? What are the costs and how many can Pentagon order per year?
As for drone swarms. Again, how much range will you get with drones? Please be specific on the size, capabilities, mission profiles and cost part of things.
Just imagining weapons is not really conducive to this conversation.
- "....move 1000 of them to Asian theater"
Don't assume they move only 1/4 of their total inventory for their primary strategic threat. It might be 3/4.
Let's say they will move more than 1000 to the theater. You still need delivery platforms. Having enough delivery platforms in the theater to even launch 400 at one burst would be quite the achievement. Keep in mind, this would also need to balance out with likely attacks in South China Sea against China's island bases. Those are clear areas that USN would have to take care of if it wants to win a battle in SCS.
Keep in mind that US dropped 700 cruise missiles in Iraq from Operational Iraqi freedom in the first 11 days.
Don't assume the actual ranges of the Tomahawk blocks because they are classified. What we do know is that the US has officially had +2500km class Tomahawks for decades. Also, as I said, it won't only be Tomahawks.
And have we seen Tomahawk been launched further out than 1500 km? What other missiles would have the range to be effective from that far out? The point is that wherever carrier group that launches tomahawk missiles are at, PLAN surface fleet and ground launchers and air launchers are likely close enough to launch retaliatory ASBM strikes. And I would be surprised if they can't muster 50 to 100 supersonic missiles at one go with all the platforms they have at disposal.
- "....they'd have to be launched from carrier group ships maybe 1000 km off the mainland shores or SSNs from 1000 km out or military bases in the first chain of island."
There's no justification to assume this limitation for the enemy. Even Basa Air Base (which is officially stated to house US material for the 'Pacific pivot') is only 1000km from the Chinese mainland. They have land within striking distance where massive missile arsenals could be already present (or being deployed slowly) without anyone knowing. We will never know the actual missile arsenal available at forward positions. Any assumption of this intel (classified at the highest level) is a mistake. Carrier Groups and SSNs will of course be part of the strike package, but no one should assume that they will be the limit. As I said, BMs will be present, and they will be used. There may also be unconventional vectors for drone swarms using cargo vessels/aircraft from closer to the coast. Also, Taiwan may be fielding part of the strike packages.
I only used carrier group as an example. They will have drones and satellites covering all of these places that might launch missiles. And as long as they fire missiles, China will be able to track it and retaliate.
China is a large country with a lot of targets and a lot of air defense, difficult terrain and strong EW pressure. A lot of targets are not going to hit the right places. A lot will get intercepted. Some with get through, but with so many targets, how can you degrade it enough. It's a strange strategy to try to beat China with the same strategy that China would use to attack US. They have different strengths and weaknesses.
All of these are valid considerations. And in evaluating them, from what I can see, the best option is to ensure that you strike first in any scenario. Because whichever side launches first will have an advantage.
No, I think you are working too hard to justify an idea that is not the biggest threat China will face. US military simply does not have enough missiles to give themselves a real advantage. China can use ballistic missiles because they are cheap, abundant and have fewer targets. Even for China, it does not make sense to use ballistic missiles for repeat strikes.
The issue is that nuclear submarines can't be used in the Taiwan Straits because the water is too shallow and there are too many Chinese ships and aircraft overhead.
And if you use submarines as missile carriers, they are awfully expensive platforms and the individual missiles can still be engaged from a reasonable distance. Plus how would you coordinate a missile strike with multiple submarines?
The PLAN fleet would be operating on the other side of Taiwan and the greatest threat they face is the USN submarines. It wouldn't be from missiles, but from torpedoes. You wouldn't really want to use SSNs to launch missiles when Chinese carrier is still around. The value of sinking a Chinese carrier with torpedo is so much more enticing than targeting land base missile launchers.
Keep in mind you can hit a carrier with subsonic missiles multiple times and it will probably still be operational. 1 torpedo, it might need to go back to the port.
