The Royal Navy in 1939: On the Track of a Paper Tiger

Looking at the Royal Navy order of battle on the eve of war, it looks like a pre-eminent naval power, no longer dwarfing its rivals but certainly not outmatched by them. But beneath the numbers and classifications, the royal oak was rotting from within. British aircraft carriers were conceived as reconnaissance platforms, not strike platforms, their handful of new battleships were functionally inferior in armament, mechanical reliability and gunnery method to those on the continent, let alone US and Japanese production, their elegant six-inch cruisers outgunned by the eight-inch cruisers and pocket battleships of other navies, and their escort force woefully insufficient in anti-submarine and anti-air roles even after two decades.

On the eve of the Second World War, Britain’s Navy faced an escalating deployment crisis. Even as the defeat of France approached, the British Cabinet persisted in trying to persuade Italy to adopt a neutral position. When France fell…

Rafale vs F-35 dogfight performance

Posted by picard578 on October 11, 2014

1) Rafale will not be entering dogfight with its full external load. Fuel tanks will be dropped, and all but wingtip missiles expended, prior to the merge. Empty hardpoints and wingtip missiles cause relatively minor drag penalty, one that cannot negate F-35s far higher baseline drag.

2) Performance penalty due to external carriage is only really relevant when baseline performance is the same, but Rafale has far better baseline performance than the F-35:

2.1) Rafale’s wing loading at combat takeoff weight is 325 kg/m2, which is less than the F-35s wing loading at combat weight (428 kg/m2). Difference is 32%. At combat weight, Rafale has wing loading of 275 kg/m2 (difference 56%). Read the rest of this entry »

Fighting in Iraq and its lessons

Posted by picard578 on October 4, 2014

Despite Iraqi Army having the most modern US equipment as well as large numerical advantage, it has performed badly against Islamist fighters of ISIS (Islamic State of Iraq and Levant, also called ISIL). Before going into how and why, a little history is needed.

ISIS has first appeared on scene after the US invasion of Iraqi in 2003. It was taking actions to broaden the scope of Sunni-Shiite civil war in Iraq by targeting Shiites, and it has been trying to take over Shiite territory for far longer.
