This week “Space Daily” re-posted an item from the Russian news outlet “Sputnik.” The article claims that the nation’s long standing expertise in electronic warfare has culminated in the ability to neutralize aircraft carriers, and that this will be demonstrated at the MAKS-2015 airspace expo happening this week in Moscow.

Irrespective of the validity of this claim, Russia does have a long history of effective electronic warfare, especially jamming GPS.

As early as 1997, Russia had developed and deployed portable 4 watt GPS jammers that were effective to 150-200 km. 

Russian jammers have been so effective that in 2002 the US Army purchased almost $200,000 worth of jammers from a Russian company.

GPS jamming by non-western forces has been a regular problem in the Ukraine.
