Note the boarding weapons on racks on the left side of the picture, including cutlasses and Lefaucheux Mle1858 revolvers. The Colbert-class ironclads were also armed with, beside a variety of other naval guns, more than a dozen Hotchkiss 37mm revolving cannons, four 356mm torpedo tubes and a ram.


WWII - French submarine “Surcouf”

Before the Second World War, the Surcouf was the largest submarine in the world. Not only was she armed with torpedoes, she also had two 8 inch (203m) cannons mounted in a turret forward of her conning tower and a airplane housed in a watertight, pressure resistant hanger behind the conning tower. Having avoided falling into German hands by escaping to the United Kingdom , the Surcouf fought along side the Free French Forces During the Second World War. On February 18th, 1942 she sank with all hands lost following a collision with a US merchant man in the vicinity of the Panama Canal.

spones-in-my-bones  asked:

Spock watched as McCoy's body took in the last light it ever would before the casket lid closed, encasing it in it's now lasting darkness. Only in death was the doctor so still, and it unsettled Spock down to his core, shook him at every nerve his Vulcan stoicism couldn't reign in. Despite the longer lifespan of Vulcans, he had still illogically expected the doctor to outlive him, if they were to both pass naturally. Even though the facts were against him, Spock still expected... no, he hoped.

“Quit yer moping, I’m right here.”

Spock frowned at Leonard’s katra. “You know it is not the same.”

Their conversation was internal. No one around them would suspect that Spock still harbored a piece of Leonard within him. Leonard’s katra seemed to take physical form beside him, slightly translucent, blue eyes still bright even in death. “Seems fine to me.”

“You are dead,” Spock thought miserably.

He felt–something. He looked down and saw that Leonard had manifested to touch his arm. It didn’t feel exactly like a physical touch, but he still felt it. The psi energy vibrated against his skin.

“Hey,” Leonard said. “I can’t have you mourning me when I’m right here to hear it.”


“Don’t make me hijack this body.”

Spock’s mouth shifted inward as he suppressed a smile. He knew Leonard could still feel his happiness, but the suppression was a habit as ingrained in him as loving his ashayam. “Consider it ‘pay back’ for your own mourning after my death.”

“Hey, that was one time.”

“That is a gross underestimate, but I can clearly recall the time you are thinking of.”

“What? I didn’t mourn! I was damned happy not to have to deal with you.”

“’I’m going to tell you something I never thought I’d hear myself say,’“ Spock quoted.


“‘But it seems I’ve missed you…’”

“You’re taking that out of context!”

“‘And I don’t know if I could stand to lose you again.’“ He arched his brow. “Were those not your words to me?”

Leonard grumbled at him. “Maybe.”

“I was in your mind, Leonard. I know what you said.”

His katra shimmered. “…Yes. I had missed you.”

Spock focused hard and reached out, his psi energy resting against the imagined-face of his beloved. No, not imagined. It was real. Merely non-corporeal. “As I miss you now. I am pleased we are still together, but my mourning is…not logical in this regard.”

“… I understand,” Leonard said after a moment, resting his cheek in Spock’s palm. 

They stayed like that–Spock breathing, Leonard not–until the boatswain’s whistle blew and Spock opened his eyes in time to see the torpedo tube launch. Beside him, Leonard glowed brightly, lovingly, and curled a whisper of kindness around him. 

“It’s okay.”

Spock took a deep breath. Let it out. “Yes,” he said aloud, so that the assembled crew looks at him in confusion. “It is okay.”


U-boote heraus!

In the years before World War One the Kaiser became obsessed with building a navy to rival Britain.  But the magnificent dreadnaughts and battlecruisers of the High Seas Fleet were never Germany’s principal fighting force at sea - it was the notorious U-boats, who waged a new kind of war on merchant shipping.

The German navy wanted to fight, but the high command did not dare risk its darling fleet against the superior numbers of the British.  The Royal Navy adopted a chary attitude too, preferring to blockade Germany from a distance to a hammering naval battle at close range.  Thus came the U-boats.  “U-boat” simply means undersea-boat, the German word for submarine, but the U-boats developed a menacing reputation that belied their name.  They prowled the seas like packs of wolves, sinking Allied and neutral shipping and weakening the Royal Navy until battle could be joined on equal terms.

The U-boats were Germany’s trump card during the First World War.  Cut-off from vital trade by the Entente fleets, her shipping cleared from the oceans, Germany risked starvation.  The daring German high-seas raiders that garnered so much press attention during the early months had also all been swept away by April 1915.  The U-boats offered another choice. 

German submarines could take the economic war to Britain by sinking shipping.  Between January 1915 and February 1917, they did just that. In August 1915 alone the German wolf-packs sent 149,000 tons of Allied and neutral shipping to the bottom.  Neutral nations, especially America, complained when their citizens died, but the vast majority of the sinkings followed the rules of warfare, which stated that the submarine must stop its target and allow the crew to take to the lifeboats, and then sink the ship by gunfire.  This was a “restricted” campaign of submarine warfare.  It would be in early 1917 that the civilian government, agonized by the failure of the Battle of Verdun, agreed with the high command that only an unrestricted campaign could hope to bring victory.  This meant ignoring the rules of warfare and torpedoing any shipping without warning; it also meant certain American entry into the war.

It would be more appropriate to call these early U-boats submersibles rather than submarines, because they actually spent very little time beneath the waves.  They were crude, cramped, uncomfortable ships.  Diesel fumes choked up the crew - one officer recommended using opium before all trips of more than twelve hours.

Submerging left the U-boat virtually blind and inert.  Submerged submarines used electric motors to avoid burning up their air supply, which slowed them down, so diving was used usually only to torpedo a ship or to avoid detection.  Normally, a regular patrol submarine could manage a top speed of 14 knots while surfaced and 8 knots when submerged.  It carried four torpedo tubes, a 51-mm gun and a crew of 28.  Other, smaller, submarines were used for coastal work or deploying mines.  Submarines improved dramatically over the course of the war, and in the later stages some patrol vessels could make it to North American waters.

While the torpedo is the infamous weapon of the submarine, they were likely to fail beyond 800m, and rarely sank shallow-draught merchantmen.  The high velocity deck gun was more practical and more regularly used, or the crew could board a merchantman and scuttle it with explosive charges.

The decision to turn to unrestricted submarine warfare in early 1917 may have been the most important choice of the war.  Free to sink anything without warning, U-boat commanders tallied and impressive 3,844,000 tons of shipping between February and June 1917.  They came close to breaking the Entente, but Britain’s vast resources and her adoption of the convoy system allowed the Allies to hold on.  Right up to the end of the war the U-boats hurt Allied shipping, but they never again came close to forcing Britain out of the war.

History Repeats

Sealion stood inside the office in full dress blues, including his flat hat which reads ‘U.S. Navy’ in gold letting. With his seabag beside him he waited for the admiral to return so he could officially report in as part of the USN detachment on the base. It had been a long time coming, since the war and eagerly awaited to see how much things have changed between the former allied and axis navies.

CRASH! Suddenly the doors stood open and his skin went white, without a moments thoughts he whipped out his torpedo tubes and fired two shots. 

“Oh damnation…”

HMS Polyphemus in a Malta Dockyard, 1881. As the only torpedo ram to serve in the Royal Navy, she was designed to penetrate harbours at speed, sinking ships at anchor. The central torpedo tube was fit with a steel bow cap which hinged upward - reinforced to be a ram. Interesting hydrodynamic effects were observed on this ship, being quite by accident one of the first bulbous bows. 

The ship found a place in the H. G. Wells’ novel The War of the Worlds, in which one HMS Thunder Child- a torpedo ram - comes to the aid of evacuees, felling a martian tripod and damaging another.

Let us be abundantly clear, Cote De Pablo left NCIS because CBS refused to treat her equally to her male co-stars, both in matters of pay equity and story content. They literally refused to treat her equally, a woman (of colour, mind) had to fight tooth and nail and they still wouldn’t do shit, so she left and she didn’t come back. 

You don’t get to praise women who speak out about demanding to be treated equally to their male co-starts ONLY when it works out for your own agenda. Cote De Pablo stood up for herself, she stood up for women and female characters and she got nothing for it, she didn’t get accolades because she’s not as famous as some of the A listers who do it and get press for it and lauded subsequently for doing so. 

But let us be clear, what Cote De Pablo did was the same as any woman whose gotten press lately for achieving something against sexism in TV, she just didn’t win against the corporations. What she did was just as amazing and strong and fortified, possibly moreso because she stuck to her guns and lost out for it. 

Don’t you dare say any shitty story on NCIS is her fault, she left partly because of the shitty stories. Don’t you dare have a go at this woman for anything. The NCIS writers not being able to treat women as actual people has nothing to do with her and everything to do with their own inherent shittiness. 

Cote cares about Ziva and refused to return only to take part in demeaning her. She portrayed her wonderfully, and I am thankful for that, and I am also thankful that she thought so much of her that she wouldn’t personally stain her memory. 

This is not her fault. Look at the NCIS writers, look at the CBS executives. This starts and ends with them. 

anonymous asked:

NEED FRENCH NAVY STUFF PLS surely their LaFayette frigates are cool?

They surely look cool, but they’re so poorly armed one wonders why the fuck they didn’t just built a cheap missile boat:

A 100 mm automatic gun, that’s good but basically standard; 8 Exocet III missiles, basically standard too for any modern warship of a relatively well-funded navy (side glances Britain); a single Crotale missile CIWS, which in itself its OK, nothing special like the italian DART or German RAM, but far better than the American Phalanx, BUT the thing is, as their main air defense system is completely anemic, basically limiting their air defense to a few seconds before impact.

What else? A pair of MANNED 20 mm guns, basically to deal with Somali pirates and the like, and… That’s about it, no VLS for better SAM systems or even ground-attack missiles, no torpedo tubes for ASW torpedoes, which would be pointless anyway as they don’t even have a fucking sonar, and their radars aren’t even that good too, just enough to have enough awareness of their immediate surroundings. 

I mean, they do have a landing path and hangar for a helicopter, with could be the ASW version of the NH90, at least helping them to fight submarines, but without a towed sonar they’re pretty limited in that function, and without a long or even medium-range SAM system they’re fucked anyway. 

Sure, their lines are clean and cool and all that, but these ships are just armed OPVs and nothing else. 

“But Enrique, the French have the Horizon air-defense frigates (destroyers), surely with those they can protect the La Fayette units from air attacks”

And you would be right, alongside their Italian cousins, the Orizzonte-class, and their British counterparts, the Type 45-class, these are the best non-AEGIS air defense warships in the world, BUT there’s one big problem:

There’s only two of them

And another

They’re tasked with defending the sole french aircraft carrier, the Charles de Gaulle. 

So no anon, the La Fayettes aren’t cool. 


“Where am I? I gotta find my bearings…” Sealion was sent on a training recon mission, it was the ususal: find the location, mark your route and time, make it back. However this island was taking nearly halfway across the world. His batteries was almost out and oxygen tanks depleted. “I have no choice…” With that he began to rise to the surface in a frenzy of bubbles. Unbeknownst to him a ship passing by just nearly cut him off. “F-Friend or foe?!” He stuttered and presented his forward torpedo tubes.


The last resting place of the Widow Maker K 19 which was portrayed by a Juliet class Soviet submarine. She presently rests just outside Providence harbor in Rhode Island at Sim’s scrapyard. the entire top of the submarine has been removed and the internals of the vessel have been completely gutted. Pumps, piping and vent openings can still be seen on the port and starboard sides. The interior separation between the inner Hull and the outer hall (or pressure Hull ) can be seen from above.
In a few of the photos taken on her port side you can see the rubber matting anti sonar coating falling off in large sheets.
When looking forward from aft to the bow you can see the remainder of the four torpedo tubes that was her primary armament.
The first image shows her circa 1999 underway. Once primary filming of the movie was completed the submarine was towed to Newport Rhode Island with hopes of making the vessel a museum. There was no funding available and the plans fell through the submarine laid up in Newport for several years before ending up in the scrap yard in Providence Rhode Island.
When crossing over the bridge from East Providence to Providence the vessel can vaguely be seen off the left side of your vehicle at low tide.
The vessel sits in a collection of abandoned industrial equipment deck barges and fishing vessels all being sent to the scrap yard. Presently in and around the shoreline is being monitored by the Rhode Island Department of environmental protection for dangerous levels of PCB’s.

November 26, 1916 - French Battleship Suffren Torpedoed in the Mediterranean, Lost with All Hands 

Pictured - A painting of Suffren bombarding Turkish positions during the Dardanelles expedition.

Geography and superior numbers assured Entente control of the Mediterranean, but German U-boats took a heavy toll there in the second half of 1916. On November 26, one of them, U-52, sank her off the coast of Lisbon with all hands, as the Suffren headed to Lorient for a refit after patrolling the Greek coast. The captain of the German submarine recounted the event in his diary:

“On my starboard side, around 08:30, I can see the masts of a warship that is heading north.  I ask for a fast dive.  She’s a large ship with two chimneys, and I believe that she is from the Formidable class.  She doesn’t have any escort and is running straight north.

I maneuver so to attack her from the front.  I am trying to stay at attack speed, but the surge prevents us to stay submerged.  We then decide to go half speed, but realize that we’d get too close.  So, we change our course to attack from a different angle while preserving the possibility to attack from our aft tubes.  They are ready and filled. This maneuver makes the submarine’s aft very heavy and her kiosque is not submerged anymore when we are about 500 meters from our objective.  I ask all crew members to get to the front of the boat, to keep her at combat depth.

At 08:56, I order to fire from torpedo tube number 2.  As I believe that I’ve been spotted, and because I am in front of my target, I am afraid that she will ram me, and I order an immersion at a depth of 20 meters, while ordering a crash port turn.  In the meanwhile, after 18 seconds, I can her a first explosion, rapidly followed by a heavier one, which shakes our boat.  To find out what is going on, I ask to go up to a depth of 11 meters.  Before we are even to the desired depth, we are again getting very heavy in the aft section.  A little later, we hear a loud noise and something scratching against our hull.  We cannot maneuver our periscope, which is stuck at mid-height.  I try again to reach our new depth.  We can’t hear anything but I can eventually reach periscope depth.  On the rear, I can sea a very large blot as well as some smut.  I order the boat to surface and I go outside.  Seven minutes after I launched my torpedo, all I can see is an explosion cloud that is dispersed by the wind.  My explanation of what happened is that the torpedo provoked an internal explosion, which made the ship sink almost instantly, almost colliding with our submarine while she was going down.  I have some damage on the bridge as well as some scratches on the periscope.  I can also see some cloth on my radio mast, as well as a navy hat.  They smell of burn.  I also found a metallic piece that seems to come from a large caliber projectile.

At 09:03, I have not found any survivors or new evidence.  I continue my route.”

All 648 crew of Suffren perished with their ship.

German cruiser Lützow (formerly Deutschland) with a snapped off stern in Kiel harbor sometime after April the 13th, 1940. The damage was caused by a torpedo hit from the submarine HMS Spearfish on April the 11th, during Operation Weserübung, the german invasion of Norway.

Notice the missing aft triple-torpedo tubes, removed while in port to begin the extensive repairs, which would take over a year to complete.


Surcouf was a French submarine ordered to be built in December 1927, launched on 18 October 1929, and commissioned in May 1934. Surcouf – named after the French privateer Robert Surcouf.

Surcouf was designed as an “underwater cruiser”, intended to seek and engage in surface combat. For reconnaissance, she carried a Besson MB.411 observation floatplane in a hangar built abaft of the conning tower; for combat, she was armed with six 550 mm (22 in) and four 400 mm (16 in) torpedo tubes and twin 203 mm (8 in) guns in a pressure-tight turret forward of the conning tower. This is one of the biggest submarine of the Wolrd War II.

Length: 110 m (361 ft)
Beam: 9 m (29 ft 6 in)
Draft: 7.25 m (23 ft 9 in)

Surcouf may have been sunk on 18 February 1942 about 80 mi (70 nmi; 130 km) north of the Panama Canal.. The wreck would lie 3,000 m (9,800 ft) deep.

Hit by sea mine ? hit by the American freighter Thompson Lykes ? German U-boat ? or friendly fire (sunk by the British or by a Polish destroyer) ? Several theories exist.

Remember, 126 crew members died that day. 



In many ways H.I.J.M.S. I-400 was decades ahead of her time.  She was the world’s largest submarine, with a length of 400 feet and a surfaced displacement of 3,530 tons.  Above her main deck rose a 115 foot long, 12 foot diameter, hangar housing three torpedo-bombers.  These floatplanes were rolled out through a massive hydraulic door onto an 85 foot pneumatic catapult, where they were rigged for flight, fueled, armed, launched, and, after landing alongside, lifted back aboard with a powerful hydraulic crane.  The I-400 was equipped with a snorkel, radar, radar detectors, and capacious fuel tanks that gave her a range of 37,500 miles: one and a half times around the world.  She was armed with eight torpedo tubes, a 5.5 inch 50 caliber deck gun, a bridge 25mm antiaircraft gun, and three triple 25mm A/A mounts atop her hangar.  The advent of guided missiles and atomic bombs transformed her from an overspecialized undersea dinosaur to a menacing strategic threat.  Like Germany’s Type XXI U-boat she was too late to influence World War II.
