Since 1998, the Trident programme has been the only operational nuclear weapons system in British service.

Until a year ago, the Trident program had been on schedule and on budget, in contrast to many other weapons programs.

Instead, the Trident program has annually sailed through Congress with breadth of support rarely found for strategic weapons.

The Trident program could be slowed by budget cuts or an arms agreement.

The overall Trident programme continues to progress to time and within budget towards an in-service date of the mid-1990s.

The Trident programme continues on time towards its in-service date at an estimated final cost of £10,518 million.

The Trident programme remains on time and within budget.

One forecasts a huge increase in the ever-escalating costs of the Trident programme.

The total cost of the Trident program thus far came to $39.546 billion in 2011, with a cost of $70 million per missile.

We should be told that we must stop the Trident programme, because that is the proper way of doing things.
