(RCS) reduction features have been incorporated into the
Formidable class design, with inclined hull sides and bulwarks as well as concealment of ship boats and replenishment-at-sea equipment behind low-RCS curtains. The
Formidable class have a significantly reduced profile than the
La Fayette class and its other derivatives, due to the smaller superstructure and the use of enclosed sensor mast technology. The frigate is also constructed entirely of steel, unlike the
La Fayette class which makes extensive use of weight-saving composite structures in its aft superstructure block. The frigates also possess better sea keeping qualities and are able to stay at sea for longer periods of time.

Intrepid conducted the navy's inaugural live firing of the French-made Aster 15 surface-to-air missile on 2 April 2008, off the French coast of Toulon. The frigate successfully shot down an aerial drone simulating an enemy target with an Aster missile. It was reported that the frigate sailed halfway round the world to test fire the Aster missiles due to the crowded air and sealanes around Singapore, plus the lack of an instrumented firing range needed by defence engineers to track and measure the performance of the Aster missile.
