Just over a decade ago, before the Type 45s order was secured, there was a real threat of closure and the end of an industry synonymous with Glasgow.

The yards on the upper Clyde may have reduced in numbers and the workforce dwindled from tens of thousands down to thousands, but there has been one constant throughout.

The Clyde-built quality mark is recognisable globally as a guarantee of the best craftsmanship now, as much as ever.

The Type 45's and the aircraft carrier contracts have given the two remaining yards a new lease of life and, as well as providing work for the thousands inside and many more in the supply chain outside, they have produced a new generation of skilled tradesmen and women.

The challenge for the future is to secure more commercial work to take shipbuilding forward as defence contracts can't be relied on to secure the coming decades.

The relationship between workers and unions and the management of the company, forged through a determination to win what orders were available stands Govan and Scotstoun in good stead.

The Clyde shipbuilders are not known to shirk a challenge.
