Murray puts her faith in rising stars Robson and Watson.
Great Britain open their 2013 campaign today in Eilat, Israel, with a Europe/Africa Pool B fixture against Bosnia-Herzegovina before clashes with Portugal and Hungary.
Should they top the pool and then come through a weekend meeting with the winners of Pool D, they will move into a World Group II play-off in April.
They got to that stage last year only to lose 4-1 to Sweden.
Fast forward 10 months and team captain Murray believes they are well placed to go one better and take their place in the top 16 nations in the world.
She said: "Elena (Baltacha) and Annie (Keothavong) headed up the singles last year and did an unbelievable job out here to get us out of the group.
"The younger members of the squad - Laura and Heather - have had a very exciting 12 months, they have pushed their ranking inside the top 50 and they are getting towards the top 40 which is a fabulous achievement.
"It means there is a slightly different dynamic in the team with regards the singles rankings.
"It puts us in a very strong position, the team is fighting fit and I think we are ready to fight for a place in the World Group.
"We have a great blend of youth and experience. It's a great platform and opportunity for us to move forward in the women's game."
Murray was also delighted by a draw which means not only have her side avoided Poland - and world number four Agnieszka Radwanska - in the pool phase but also a possible weekend play-off.
