The table below lists the U23 Inter Service Results (where known) from 1989.  The U23 Championship grew out of the U21 Championship when both the RAF and the Royal Navy began to struggle to raise an U21 side due to the increasing average age of their new recruits.

The U21 championship ran alongside a Colts tournament for a few years after its formation.  The Colts (U19s) Championship was also ended due to difficulties were producing sides.

In 2016 the Royal Navy U23XV retained their Inter Service Trophy, the first time that an age group Navy side had ever retained an IS title.  They were also only the fourth Navy team to ever retain an IS Title, showing how difficult the Royal Navy have found this since the Inter Services (for the men) first started in 1920.
