Preparations for Exercise Cold Response, to be held in Norway later in March, have seen the operational debut of night vision goggles (NVGs) with front-line Swedish Air Force (SAF) units. The arrival of the new system has been long-awaited by Squadron Commander Carl-Johan Edström. The use of NVGs brings particular benefits for operations in the short days of the Nordic winter.“NVGs allow us to make much better use of the dark hours of the day. Their long-term effect on flight operations will be profound” says Edström, and there are many other benefits too.Detect and identify other aircraft earlier“When using NVGs we have found that pilots can detect and identify other aircraft much earlier and over longer distances than in daylight. This is a function of the unique way NVGs gather and use the available light. It makes a big difference when undertaking close air support at night. Thanks to the NVGs a Forward Air Controller can direct air strikes using a laser beam to pinpoint the target – that beam is only visible through the image intensifiers of the NVGs.”Proven technologyFlying with NVGs is nothing new, and SAF aircraft like the Viggen and Sk 60 were doing it more than 20 years ago. Now the latest feature on Gripen, which adds a purpose-built NVG compatible cockpit, provides for seamless NVG integration and operations.“The lighting for every switch, button and display in the cockpit has been specially designed to be clear and uncluttered at all times when viewed through the NVGs,” says Carl-Johan Edström.Careful integrationIntegrating the new NVGs was a three-year process which involved a team of five test pilots working under Swedish Defence Materiel Administration (FMV) leadership. Flights started in Vidsel, Sweden, with a modified Saab Sk 60A and a year later the NVG-capable trainer was transferred to F21 Wing, where pilots started to prepare for the transition to NVG operations on Gripen.A darkness uniqueTo get the best results from NVGs requires a total darkness of the kind that, in Europe at least, is found almost only in northern Sweden. The long winter dark period there, from October to March, could permit many other air forces to come and practise their NVG operations. Across the rest of Europe the light from urban areas means it never becomes truly dark. While they may appear to be dark to us, dawn and twilight hours are too bright to permit proper NVG use, so they further shorten the time available to train with, and master, this key operational capability.Notes one Swedish pilot, “The sun must be a full 12 degrees below the horizon before you can really say it’s dark out there.”</blockquote>
