The following images illustrate the most important classes of warships that were in service with the navies of Sweden, Norway, Canada and Argentina during the World War II. All the images are created by www.naval-encyclopedia.com. In that page you can read some excellent naval history articles, to download other graphs or you can purchase the same graphs in high resolution in the online shop! More posts will follow for your collection of current naval fleets but also of fleets from the past.

FLEETS #14: Swedish Navy, Israeli Navy and Egyptian Navy today

Written by D-Mitch

This is the fifth article about various countries' navies today. In these articles, I briefly describe a country's naval fleet by reporting the ships in each type/category of warships and by providing a nice image where all the types of warships are illustrated and the units of its class are reported. I include the vessels that will enter in service this year and I have excluded those that are about to be decommissioned. I deliberately excluded many classes of auxiliary ships; those that they have "0" defence capacity and those that have secondary roles such as hydrographic survey ships, tugs, depollution vessels and training ships.

NAVAL FORCES #5: Signals Intelligence (SIGINT) collection ships of European Navies

European Navy today (2015)

Signals intelligence (often abbreviated as SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligence - abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence - abbreviated to ELINT). The data gathered are typically pertinent to the electronics of an opponent's defense network, especially the electronic parts such as radars, surface-to-air missile systems, aircraft, etc. ELINT can be used to detect ships and aircraft by their radar and other electromagnetic radiation; commanders have to make choices between not using radar, intermittently using it, or using it and expecting to avoid defenses. COMINT, as it was mentioned in the previous paragraph, it is a sub-category of signals intelligence that engages in dealing with messages or voice information derived from the interception of foreign communications. Modern navies use naval vessels with sophisticated equipment for this purpose, the so-called spy ships.
