Case study

Mitigating operational capability gaps


Storm Shadow, currently in service with the RAF Tornado GR Mk4 (Figure 1), is an air-launched stand-off missile, designed to engage a variety of ground targets. Prior to the withdrawal of Tornado GR Mk4 from service, the UK MOD aims to introduce the missile onto EF Typhoon (Figure 2) to avoid a real risk of operational capability gap.
The Air Dominance and Suppression Project Team (ADS PT) required safety and environmental support to ensure the risks associated with the use of the missile were As Low As Reasonable Practicable.


Frazer-Nash supported the ADS PT with ongoing management of the Storm Shadow missile safety and environmental case for carriage, release and jettison from Tornado GR Mk4, and independent safety advice towards missile integration onto the EF Typhoon. We provided a dedicated team of air platform / weapon experts to deliver coherent, robust and timely safety and environmental support to the ADS PT; providing continuity (over eight years) to the Storm Shadow programme.

Our support included development of the Tornado GR Mk4 centric Storm Shadow missile safety argument structure, and independent technical evaluation in aid of EF Typhoon ground, air and avionics, evidence gathering flight trials. Given the difference in operating environment and envelopes between the Tornado GR Mk4 and EF Typhoon platforms, this involved an in-depth knowledge and understanding of a number of key weapons integration considerations / principles. Frazer-Nash support to the Storm Shadow programme included:

  • Development of the Safety Argument Structure
  • Authoring the Safety and Environmental Management Plan
  • Hazard Identification and Analysis workshops
  • Development of the Hazard Log
  • Authoring the Safety and Environmental Case Report¬†
  • Support at the Project Safety and Environmental Panel meetings
  • Supporting Ordnance Munitions and Explosives, Safety Review Panel submissions¬†
  • Legislative compliance assessment
  • Life Extension Assessments
  • EF Typhoon Flight Trial Capping Paper assessments
  • Periodic Independent Safety Audits
  • Management of the Livefiles technical repository database

The support Frazer-Nash provided to the ADS PT culminated in the first release of a Storm Shadow missile from the EF Typhoon aircraft in November 2015. Squadron Leader Ross Clarke, ADS PT Weapons Integration Programme Manager, stated that "Frazer Nash helped MOD Weapon and Platform Project Teams understand and articulate the relevant safety arguments enabling a successful trials programme''.
