clip Canada Day colour scheme?

July 01, 2015, 02:05:42 by MCG
Lots of black and red.  I assume this is a Canada Day theme, but it looks more like crimson apocalypse.  I cannot even see the underline to warn of my spelling mistakes.

xx Hearing talk that Salt and Peppers are leaving too

June 10, 2015, 16:06:09 by jollyjacktar
Not that I am bitching, and would have included this in the other thread Loach has locked.  But, on the buttons and bows scene, I heard today some scuttlebutt that Salt and Peppers are on the way out along with the new changes proposed to the NCD's.  Some savings to be found there with cutting back on the orders of dress.  NCD's or DEU as the situation dictates.  Less BS.  I like it.

xx How the Navy treats its kids ... er, sailors (From: Re-Royalization)

May 25, 2015, 01:33:06 by medicineman
FDU(P) like FDU(A) are just far enough away from the adults that they can get away with quite a bit, same as with the DC schools.

Funny you used the term adults...since we were actually treated that way, vice units elsewhere...including my own Mothership.  I figured that after 20 something years of service and a Crown on my uniform that I was no longer a Private but was soon mistaken  ::).

icon2 Plundering navy war graves

April 23, 2015, 12:28:21 by E.R. Campbell
This, reproduced under the Fair Dealing provisions of the Copyright Act from The Telegraph, is a dreadful thing:

Wreck of HMS Repulse 'rigged with scrap metal merchants' explosives'
Divers cut fuses attached to home-made bombs in an effort to protect war grave off Malaysia

By Julian Ryall, Tokyo

8:00AM BST 23 Apr 2015

The wreck of HMS Repulse, sunk in 1941 off Malaysia and classified as a war grave, has been "rigged up with home-made bombs and fuses waiting for detonation", according to a diver who visited the site on Sunday.

David Yiu, director of Singapore-based Friendly Waters Seasports Pte., dived on the battlecruiser to place a memorial flag in honour of the 508 men killed when the ship was sunk on December 10, 1941, by bombs and torpedoes dropped by Japanese aircraft.

Despite being a war grave, scrap metal merchants have been illegally plundering the wreck, as well as that of HMS Prince of Wales, which went down just 9 nautical miles away.

"New fuses and cables had been laid all across the hull and tin cans containing explosives were in place", Mr Yiu told The Telegraph. "And they had only been there a short time because there was no marine growth on them."

Mr Yiu and his colleagues cut as many cables as they could find, as well as the scrap metal merchants' mooring ropes.

"It was going on nearby when we were at the site because we heard a loud 'boom' when we were diving", Mr Yiu said. "It was so loud that I thought it had come from the Repulse.

"When we got on the deck, we looked through binoculars towards where the Prince of Wales is, but there were no ships there", he said. "They must have been after some of the other wrecks that are in the area, such as the two Dutch submarines."

Divers inspect wreckage of HMS Repulse

Mr Yiu says the damage being done to the British warships is "hugely disrespectful" to the men who died when they sank, while another concern is the environmental damage the vessels could cause should they leak large amounts of fuel.

"They have already stolen the propellers from the Repulse, they have pretty much blasted all the back section away and when I was last on the Prince of Wales there were huge sheets of metal that had been blown off the hull and were ready for lifting.

"And the wrecks were not leaking oil before because their hulls were intact, but the blasting has damaged the plates and knocked the rivets out, so the oil has started to seep out", he said.
In November, the Malaysian navy impounded a Vietnamese-flagged fishing vessel that was caught with divers in the water on one of the wrecks.

I hope these guys are caught and tried and convicted in Singapore ... where flogging is still a normal punishment for many offences.

xx AIP subs

April 10, 2015, 10:51:53 by Thucydides
This article from NextBigFutre goes on about the relative advantages of AIP subs, which are much cheaper than nuclear SSN's. What is missing from the analysis is the drawbacks (besides having some pretty complex machinery packed in the hull), most particularly the sustained high speed ability of a nuclear submarine. Special infrastructure for loading submarines with liquid oxygen is also needed for some designs of AIP submarines. If I were designing an AIP sub, I would be looking carefully at an option not explored here; Solif Oxide Fuel Cells (SOFC) which can turn hydrocarbon fuels directly into electrical energy, eliminating the need for multiple types of machinery and limiting the need for liquid oxygen for submenged operations (since SOFC and fuel cells in general are far more efficient in converting chemical energy from fuel into electrical energy than diesel engines).

For a nation like Canada, with a long coastline and a need to deploy up to halfway around the world, this is an important factor for planners to consider as well:

New Air independent propulsion subs at less than half the cost eliminate the reasons for nuclear submarines
Nuclear submarines had certain advantages over diesel submarines. Nuclear submarines had greater submerged endurance of 90-100 days versus 3 days for conventional submarines. This was limited by the amount of food that could be carried. Nuclear submarines also had higher speed.
Air independent propulsion (AIP) submarines use fuel cells, stirling engines, batteries or liquid oxygen storage for closed cycle diesel engines or close cycle steam.
AIP submarines are quieter
While nuclear submarines have measures to reduce sound and magnetic signatures, nature of nuclear propulsion (steam turbine) makes them far more noisy than AIP submarine of same size. They also tend to be larger on a whole, making them even more detectable through either acoustic, infrared or magnetic sensors. Further weakness of nuclear submarine is that it has to cool down nuclear reactor, with hot water being dumped into ocean, leaving long trail behind the submarine; as such, it is even more detectable by IR sensors than just size difference suggests.
Nuclear submarines have cruise speeds of 20 – 25 knots, compared to 10 – 15 knots for AIP subs. Combining slower cruise speed with bursts of high speed can allow AIP subs to cover relatively large area. They can deny access to enemy nuclear submarines. HDM and MESMA systems used in AIP subs (submarines using them typically cost 250 million USD) are far quieter than nuclear plant.
Using traditional diesel engines, a fuel cell, large lithium-ion battery pack, and liquid oxygen to replace the air normally used in combustion engines, the SMX-Ocean sub concept could stay off-shore in deepwater operations for 90 days at a time. The AIP system also allows the sub to remain submerged for up to 21 days at a time, and gives it a range of about 18,000 miles at an average speed of about 10 knots.
Here is details of AIP technology and capabilities.
Submarine snorkling for oxygen can be detected with new radar
Batteries continue to improve
The Lithium ion batteries for the Soryu and SMX-ocean are getting higher energy densities and lower costs because of the success of electric cars like the Telsa Model S. These will further increase the advantages of the AIP submarines.

AIP submarines cost $100 million to 900 million. The AIP models with the greatest market success are the Japanese Soryu ($600 million), Russian Kilo ($350 million), Swedish Gotland ($365 million), Spanish Scorpene ($500-800 million). They can be submerged for about 14-21 days.
The Gotland and the other AIP are very capable submarines.
The nuclear submarines are $1.3 billion to 3 billion. The equivalent AIP submarines are half to four times cheaper.
Nuclear submarines may see a revival in cost effectiveness in 15-20 years when a new generation of molten salt reactors become available. However, for now there is little reason economically or militarily for nuclear submarines.
Nuclear submarines have 20 megawatts of power compared to 3 megawatts for diesel submarines. There is no need for high power for any new laser or other weapon systems.
The US is looking to add unmanned submarines for about $40 million each. Capable unmanned submarines seem to be 5-10 years away. The unmanned systems could track other submarines or operate as part of pack working with a primary manned mothership submarine.

Any current or former naval electrical technicians who may be interested in working off-shore Canada in oil and gas in the immediate future, send me a PM.
