Farewell to Athabaskan

After paying off during the winter of 2017, the former HMCS ATHABASKAN has been alongside in HMC Dockyard having various equipment removed and being prepared for breaking up. I covered her final week in commission and her paying off ceremony here.

With all the preparations complete, Athabaskan was schedule to leave first at 1000 on Wednesday March 28, which was then delayed until 1700 that day, but she instead finally left Halifax on March 29 under tow for Sydney, NS, where she will be broken up. The later timing worked much better for me, as I would otherwise have missed it. 

I rode the Halifax-Dartmouth ferry back and forth from 0800 until 0915 or so to get these images, and was fortunate that the ferry was able to pass ahead of the tow on her final Dartmouth-bound crossing - which is exactly what I was hoping for! 

Atlantic Larch was alongside the jetty hooking up the towline when I arrived at the ferry, and she was shortly joined by the Navy tugs Glenside and Listerville to help ease Athabaskan out into the stream.

Athabaskan shortly after the tow began, with Atlantic Larch in the lead and Glenside still with a line to the quarterdeck. A backup towline is rigged at deck level along the starboard side - to be used if the primary tow line breaks during the tow.

Other ships have been towed via a bridle connected to the two anchor chains, however, Athabaskan only has the one anchor chain on her starboard side, so the tug is connected to a line threaded through the bullnose. Another line hangs from the starboard bow, possible one of her mooring lines improperly stowed.

This is the specific shot I was hoping for - a portrait image of Athabaskan and her tugs.

My final sight of Athabaskan - the obligatory shot of her with the George's Island lighthouse in the foreground.

When she was paid off, Athabaskan was the only destroyer in commission with the Royal Canadian Navy, and it is unclear whether the RCN will ever have another - it is quite possible that the proposed Canadian Surface Combatant (CSC), the class of 15 ships slated to replace the IROQUOIS and HALIFAX classes, will be classified as frigates. Regardless of whether new ships are classified as frigates or destroyers, the IROQUOIS class, and Athabaskan as the final representative of that class, was probably the last destroyer (for a while at least) entirely designed and built in Canada, as the RCN is currently looking at foreign designs for CSC.

Farewell, Athabaskan!

HMCS ATHABASKAN

The Royal Canadian Navy has announced in the last month or so that HMCS ATHABASKAN will be paid off from service on March 10. Commissioned on September 30, 1972, this will give her just shy of 45 years of service. The four IROQUOIS class destroyers were a great leap forward when they were introduced in the early 1970's and received mid-life refits to provide Area Air Warfare (AAW) capability in the early 1990s. HURON was paid off in 2005 (and later sunk for target practice during an exercise) after being laid up for a few years, and ALGONQUIN was paid off in 2015 after making contact in 2013 with HMCS PROTECTEUR during a towing exercise which resulted in her port hangar getting shredded. IROQUOIS was also paid off in 2015 after worrying cracks and rust were discovered in critical locations. IROQUOIS and ALGONQUIN are both currently in Liverpool, NS, for breaking up.

ATHABASKAN is now the last of the four ships in service.

After the previous RCN classes of anti-submarine destroyers (other navies classified similar ships as frigates), the IROQUOIS class introduced a number of new concepts to the RCN (indeed, some were new to the navies of the world) including all gas turbine propulsion (in a COGOG arrangement), air defence missiles, and a hangar for two large anti-submarine helicopters. They were proper destroyers. I will borrow some text from my summary on the Hazegray and Underway website:

"These four ships were the first warships in the world to depend entirely on gas turbine propulsion (COGOG). Economical cruising power was provided by two efficient cruise gas turbines, while high speeds of up to 29 knots or greater could be reached with two boost turbines. When commissioned, they were excellent ASW platforms, and were the first Canadian destroyers to carry two helicopters. Based upon the hull design of the cancelled 1960s era General Purpose frigates, they were instantly recognizable due to their infamous 'playboy bunny' funnels. Command facilities were included in the ships. This class of ship influenced the design of the USN's SPRUANCE class destroyers. 

As built, they were armed with a quick-firing OTO Melara 5"/54 forward, which provided them with good anti-surface and naval gunfire support capability, as well as close-ranged anti-aircraft defence. Point anti-aircraft defence was provided by NATO Sea Sparrow missiles, launched via a one-of-a-kind twin quad launcher situated just forward of the bridge. No other ships, in any navy, used this system. The missiles would be trained outboard of the launcher (in the deckhouse forward of the bridge) on launcher arms port and starboard, with four missiles to an arm. The arms would be brought back inboard for reloading. Anti-submarine capability was provided by two Mk.32 triple torpedo launchers, port and starboard, in addition to helicopter launched torpedoes. As well, a single Mk.NC 10 Limbo ASW mortar was provided in a well in the quarterdeck, aft of the helicopter deck.

At the time, much was made of the fact that these ships tied together, in a viable package, an Italian gun, American missiles and torpedoes, Canadian sonar, and a Dutch radar and fire control system.

During the Gulf War of 1990/91, ATHABASKAN was sent to the Persian Gulf along with two other ships. She was quickly upgraded with a new mine-avoidance sonar, along with a Phalanx 20mm CIWS (mounted over the Limbo mortar well) and shoulder launched Blowpipe and Javelin missiles. When USS PRINCETON was disabled after hitting a mine in the northern Gulf, ATHABASKAN escorted a tug to her rescue and escorted both ships back out through the minefield.

In the late 1980s / early 1990s, these ships were modified under the TRUMP program. This refit program saw the installation of new anti-aircraft missiles, main gun, radars, fire control system, and the addition of a CIWS gun system."

Looking out over ATHABASKAN's modernized foc'st'le, with the new 76mm gun and a 32-cell Mk.32 vertical launch system taking the place of the original 127mm gun.

The TRUMP refit changed the appearance of these ships, but if you look at them the right way their impressive lines are still apparent.

ATHABASKAN was on display, and open for tours, during the RCN's centennial in 2010.

Although too late to photograph any of these ships in their original configuration, I have captured a large number of images of ATHABASKAN since the mid-1990s. I will show some of my favourites here.

A scan from film, this is one of my earliest images of ATHABASKAN. She had not yet been fitted with the SATCOM domes either side of the funnel at this point. This was probably taken in the 1990s.

Another, later, scan from film, this time from the early 2000s.The starboard SATCOM dome is now present.

ATHABASKAN was the review ship for the Tall Ships Parade of Sail in 2004. She is shown here saluting Pride of Baltimore II.

Part of the TRUMP refit was the addition of modern Command and Control facilities, and the IROQUOIS class were prized for their ability to lead a task group. Although this ability has been retrofitted to the HALIFAX class frigates during their FELEX mid-life refits, the latter's reduced accommodation space makes the ships rather cramped when fulfilling this role compared to the older destroyers. For ATHABASKAN, this led to leading roles in disaster relief missions to the US after Hurricane Katrina (Operation Unison) and Haiti after a 7.0 magnitude earthquake (Operation Hestia). 

ATHABASKAN was one of four ships sent south to help with Hurricane Katrina recovery in 2006 (Operation Unison).

After ATHABASKAN's last refit in St. Catharines, ON, she was towed to Halifax and broke her tow, sustaining some hull punctures during her recovery. Possibly due to the additional repairs required, her reduced remaining lifespan, or a combination of the two, ATHABASKAN was not fully reassembled after this refit. When she returned to service in 2013 for sea trials, she was missing her long range air search radar and fire control directors (and with them her ability to fire her long range air defence missiles) and torpedo tubes, in my opinion removing most of the capability that made her a destroyer. The variable depth sonar (VDS) had been removed prior to the last refit. She still retained her command and control facilities, however, and was still useful to lead task groups including the RCN contingent during the 2016 Cutlass Fury exercise.

The missing VDS is apparent in this photo.

Although all four ships had their cruise engines replaced in the 1990s, ATHABASKAN has tended in recent years to produce lots of smoke while the engines are fired up (although I have seen a photo from the 1970s recently where she was doing the same thing - so maybe she just has bad habits).

For the last photo, we will pretend this is an appropriate sunset (it's actually a misty sunrise).

ATHABASKAN is the only one of her sisters that gets to pay off on a high note (knock on wood) and go straight to being paid off from active service - her sisterships all paid off after an inactive period alongside. ATHABASKAN is still at sea as I write this, mere weeks before her retirement.

The impressive appearance of these ships will be missed by this photographer.

Harbour Photos this Week: October 24-28

Riding in HMCS SACKVILLE back to the Dockyard (covered in a separate post) was definately the high point of my week, photography wise, but there were a few other things to catch my camera's attention. I will start with some incidental photos taken during SACKVILLE's transit.

Wednesday I was in meetings in Dartmouth, and didn't get to see what was in the harbour, but on Thursday the French Navy's offshore patrol vessel BOUGAINVILLE departed. She had been visiting the Dockyard for the week.

In a relatively rare occurence, there were two cruise ships overnighting on the seawall on Thursday, and the Port of Halifax was kind enough to tweet this news to area photographers. I didn't get the best photos, but here they are:

There were also some interesting sunrises and other cloud effects this week, two of which I captured and will show here.

I will finish with a photo that wasn't taken this week, but which I finally got around to processing this week.

Morning Harbour Traffic

When I arrived at the ferry this morning, there were two ships at anchor hiding in the snow squall that enveloped the harbour. One was HMCS ATHABASKAN, after arriving earlier in the morning, with a geared bulker in the foreground (whose name I did not record):

The snow squall eased a bit shortly after I took this photo, enough that I could see out into the harbour approaches as CCGS Sir William Alexander approached George's Island.

When conditions are right, you can see the ship's wake stretching out to either side for quite a distance.

Last of the 280's - HMCS ATHABASKAN

Once upon a time, there were four IROQUOIS (DDH 280) class destroyers, all of which were commissioned into the Royal Canadian Navy during the early 1970s. Wonders of modern warship construction at the time, they received extensive upgrades in the 1990s to transition from antisubmarine warfare (ASW) destroyers to guided missile area air warfare (AAW) destroyers. This bought them, in some cases, another 20 years, but now only one remains: HMCS ATHABASKAN (DDH 282).  HURON was paid off first, and sunk in an exercise. IROQUOIS and ALGONQUIN both paid off this year.

PRESERVER (left) and ATHABASKAN are the two oldest warships ships remaining in RCN commission. ATHABASKAN is the only one of the two still serviceable, with PRESERVER sadly operating as a glorified refueling barge.

Being the last of your family isn't easy. An accident during her tow whilst returning from a refit on the Great Lakes caused some minor damage, and she was never completely returned to her full fighting trim. More recently she has had propulsion problems (despite cannibalizing sister IROQUOIS for many parts). Despite this, she and HMCS HALIFAX (FFH 330) have deployed this week to an exercise in Europe. In the process of leaving on Thursday morning, ATHABASKAN circled the harbour with a Sea King on deck, which proceeded to warm up and take off before she left. My morning ferry ride put me in the right place at the right time, so to speak, to capture some of this.

On ATHABASKAN's return to Halifax from refit in 2013, several holes were visible in her hull above the waterline just aft of her pendant number on the port side, from where she hit the tug that was towing her.

I first saw her headed out beyond George's Island, after which she turned and returned to the inner harbour, with the Sea King on deck. 

Just rounded George's at this point.

Somewhere along the Dartmouth shore, as I was about to pack it in, the Sea King fired up. Around the same time, ATHABASKAN's exhaust plume of blueish smoke also became more apparent. Apparently she is still having some propulsion issues!

The Sea King continued to spin her rotors as ATHABASKAN turned to head back south. I was hoping that she would lift off before getting too far away from my vantage point on Cable Wharf, and I wasn't disappointed. 

Just after the Sea King lifted off. Note the rotor tip vapour trails.

Helicopters can be challenging to capture properly. With any prop or rotor driven aircraft, it is good practice to slow the camera's shutter speed in order to impart motion to the propeller or rotor, otherwise the aircraft can appear static in the air (as if it were falling). Plane propellers spin faster than helicopter rotors, so of the two, helicopters require slower shutter speeds. I usually aim for 1/100 of a second for helicopters, although the shots here were at 1/200 of a second because I forgot to change to shutter priority mode on the camera. Still, not too bad.

After liftoff, she moved right and flew along the starboard side of the ship.

I consulted Wikipedia about the vapour trails. Wingtip or rotor blade tip vortices are always present when lift is being generated, but are only visible when humidity conditions are just right, so that water vapour may condense or freeze in the core of the vortices. It was quite humid this week, so apparently conditions were right. You can also see the water kicked up from the harbour by the rotor wash from the Sea King.

Sea King headed back to Shearwater, ATHABASKAN passed the lighthouse on George's on her way out.

After she passed George's, I had to tear myself away to get to work. Hopefully the exercise is uneventful (well, in the bad sense anyway) for ATHABASKAN!
