No worries - was taking a friendly dig without wanting to take the pi$$ too much as is the usual PPrune manner, although this thread has been surprisingly tame of late - good to see!
Re Harpoon, the umbilical, bussing and many other elements for Harpoon Block II/III and a SLAM-ER are identical, although the Harpoon is a lighter weapon. At this time, the Harpoon has not been cleared from the F-15, but I don't imagine it would be a major program to do so.
With the SLAM-ER qualified on the F-15K, there is certainly scope to field Harpoon Block II/III in the future, although there is much cross-capability between the two missiles. As far as I am aware, the Harpoon fielded by Singapore is the Block I ship and sub launched variant.
