It will take that time to build all the tower segments, (and associated swing-arms, chopsticks, etc) and OLM parts for LC-49. Maybe they plan on having approvals by early next year to start prepping the site. They'll have the Tower and Mount ready to go. It's the only thing that makes sense. imo. Or just having spares for when they frag the tower on a catch attempt?

Or just having spares for when they frag the tower on a catch attempt?They are far more likely to damage “soft” items like hydraulic components, fluid lines, and other support system parts than structure elements of the tower. There’s not that much dense, heavy material in a returning booster compared to the mass of the tower itself, and said booster will certainly use a similar profile as a landing F9 - it will maintain an IIP well away from infrastructure until the landing burn starts. Unless the chopsticks fail entirely and break off the tower, any physical damage of a significance will probably be repaired by welding in-situ. And frankly, if the chopsticks break off the tower entirely, some engineers will have effed up years before hand anyway.

I recall a guess of 20 tonne? This might have a tendency to go boom after a bad catch.

There was talk of adding crew capability to SLC-40 as a backup in case of a RUD at 39A.That would require a tower for crew access.Something like half-a-dozen sections (give or take a couple) should give the required height. Add a crew access arm (plus maybe a lightning rod) and bingo.
These arrived at the SpaceX dock at Port Canaveral recently and were unloaded onto transport trucks. Could they possibly be Starship transport stands headed to NASA? What do you think? @FarryFaz @CSI_Starbase
I have just confirmed they are Starship transport stands headed out to Roberts Rd at NASA. Starships will soon sit on these being readied for launch on 39A!

Apart from LC-39A and LC-49 the only other place SpaceX is thinking of putting a launch and landing tower is at SLC-47 but that place is tiny and needs more development. So far no place other than LC-39A is showing any sign of getting a tower of any kind. Not LZ-1, not LZ-2, not SLC-40. Work hasn't even begun on LC-49. Any work on a third tower and its location will be seen for miles (literally, Harry will get sat pics of it and we'll know even before anyone can go fly and take pics of it).

#SpaceX is preparing to build another Launch tower at the Cape (OLIT 3.0). First indicators have been spotted a few weeks ago in one of @GregScott_photo's flyovers.Now, on the latest flyover you can see the first beams for the tower segments being prepared for assembly.
Structural steel for the 3rd Orbital Launch Integration tower has been arriving rather quickly to the Roberts Road facility. No columns on site yet.Really wondering what the timeline on that third tower is looking like @elonmusk 📸: @GregScott_photo
People are wondering where the next tower would be located why not LC-39a? They already have two towers near(ish) to each other, why not three? There seems to be plenty of room there still and both towers could share the same GSE systems.

SpaceX recently committed; to adding a tower to LC-40 for Dragon access. They could build the basic structure for that using the Starship template to save time vs creating a new design from scratch.
