With 6 T31s, it has been estimated 2 could be forwarded based (one in the Gulf and one in South Atlantic), 1 available for FRE duties, and 1 available 50% of the time for Caribbean duties. This assumes major refits occur in the UK around once every 6 years for each ship.

Of course just because a ship is forward based, does not mean it is 100% available during this period. It just means the normal periods of unavailability (maintenance, training) will occur while the ship is in its forward base.

People are confusing 'forward based' as being the same as deployed on a operation. It is not. It alters the ships pattern of working a lot.

Typically a ship would go through a long period of low readiness/refit, followed by a long period of work-up and training, before being deployed operationally for a long period (6 - 9 months).

For forward based ships, they will have many short periods of operations,and many short periods of maintenance and training, all while at their forward base.

Thanks, so how would play with a T26? I assume it will be harder due to the higher end kit, but maybe by maximising similarities between the RN and Oz version and performing some forward based servicing in Oz Yards, maybe be able to support 2 deployments (Oman/Bahrain and Singapore) with 5 ships?

You have missed the point. Forward basing 2 ships is not the same as deploying 2 ships on operations.

It will not play with T26. T26 will be supporting carrier groups and TAPS, and will not be forwarded deployed.

Aethulwulf, understand the difference between Forward Basing and Deployments sloppy wording on my part - I do not believe either really need full time RN presence, but being able to respond to events in a shorter period and having the diplomatic impact of having 1st class assets “in region” will have a big impact.

My view is that both should be forward based T26s, as these would give real value not just flag waving or limited HADR. I agree probably 6 of the current T26 fleet will be tied up on CSG / TAP / FRE duties, but with the addition of another say 3 T26s then we could achieve this.

No. Eight of the T26 fleet will be tied up on CSG / TAPS

Whether it is 8 or not (and by when), I would hope that folks around here take the above ' on authority' which is something that none of us have... but building the 'thought train' from there would stop us going in eternal circles.

Interesting note at the bottom of the latest equipment plan, it's the first time I've seen a cost associated with installing CAMM.

I assume this is on top of the £500m development fund shared with the other force's.

I assume that includes buying the missile stock?

The costs for the T23 come in at about £2million per missile (32 per T23 and 13 T23) whereas the costs for the T 26 (48 per T26 and 3 T26 on order) is about £1 million per missile. Obviously there are other costs that comprise these sums beyond the missile stocks, but what would be the reason for the costs of T23 provision being double that of the T26?

The missiles come in sealed containers so for T26 you only need an initial loadout and the rest comes from recycling them from the reducing T23 fleet?

I don't think that's a valid calculation. There isn't a permanent fit of one 1 missile to 1 silo, it's a pool of missile that rotate between on a ship, on the shelf, and back at the manufacturer.

Thanks, I get that. It was a crude calculation and I was really just asking what the discrepancy between purchases for the 2 platforms were.

I assume its because the T26 will draw from the same pool the T23 already uses.

What is included in the quoted figures? Is it the cost of the VLS, software and electronics? I doubt if the cost of the missiles is included. The discrepancy in cost could simply reflect the need to remove the Seawolf elements on T23 and fit those for Seacepter, rather than install them at build.
