£100M is a rather small amount in the world of military aircraft development and production.
For reference, Typhoon development is stated at between £20 and 37Bn, each airframe at up to £55M and "a modification programme" to enable it to do ground attack (!!) is said to be costing over £600M.
What exactly are BAe going to be doing? It doesn't sound like a large slice of a potentially huge pie.
