All three cables are being laid for the same reasons: Redundancy and speed. As it stands, it takes roughly 230 milliseconds for a packet to go from London to Tokyo; the new cables will reduce this by 30% to 170ms. This speed-up will be gained by virtue of a much shorter run:

If they could armor the cable sufficiently perhaps they could drill the straigh line path through the Earth's crust (mantle and outer core) and do London-Tokyo in less than 10,000km. Aled
