Brazilian Sao Paulo (A12) back to Sea after extensive refit, and work up of her upgraded Air Wing

Brazilian Aircraft Carrier, Sao Paulo, A12, looking very ship shape after refit/overhaul

The Brazilian aircraft carrier underwent an extensive overahaul and modernization between 2005 and 2010. (This latest information is based on articles through 2012 from Base Militar, Reuters, Flight Gobal, etc.). After the refit, it wnet through a prolonged period of working up, having its airwing upgraded and a short stint of repairs from a small fire in 2012, but is now back out to sea. The work accomplished during the major refit included all of the following:

1. Inspection and repair of the steam turbines
2. Maintenance of the surface condensers
3. Retubing of boilers
4. Repair of two high-pressure compressors.
5. Revision of the AC electrical generator.
6. Maintenance of pumps, valves, and structural items.
7. Addition of two API oil-water separators.
8. Installation of two water cooling units.
9. Upgrade of the chemical oxygen generator.
10. Repair and treatment of oil tanks.
11. Replacement of the Naval Tactical Data System
12. Installation of a closed-circuit television surveillance camera system.
13. Installation of an IFF transponder.
14. Installation of a MAGE system (ESM).
15. Flight deck inspection, repair, and painting.
16. Modernization and upgrade of the Optical Landing System processing unit.
17 Overhaul, maintenance and rrevision of the aircraft catapults.

These upgrades were completed by late 2009. A significant purchase of spare parts for the vessel was also accomplished inocnjunction with these upgrades and overhauls. and the São Paulo was initially operational by August 2010.

In addition, the twelve Brazilian Navy A-4 Skyhawks were also upgraded by Embraer at a cost of $140 million. These upgrade was similar to the ones done for the AMX and F-5EM aircraft of the Brazilian Air Force. The program included restoring the aircraft and their current systems, as well as implementing new avionics, radar (specifically the Elta 2032 radar system), power production, and autonomous oxygen generating systems. Weapons included in the upgrade were the MAA-1B, Python 4, and the Derby AAMS.

Brazil also purchased ex-Australian and ex-Uruguayan airframes EX-USN C-1 Trader airframes, for conversion into AEW planes and Tanker aircraft. Nine aircraft were purchased in total. All of the planes were upgraded to S-2T Turbo Tracker configuration with Honeywell TPE 331-14GR engines. Of the nine airframes, two were for tanker conversion to refuel the A-4 Skyhawks, four were for AEW covnersion, two were for cargo aircraft conversions and the other was for spare parts.

The Brazilian Navy contracted Marsh Aviation to convert the four upgraded S-2T Turbo Trackers to an Airborne Early Warning (AEW) configuration, and the other tankers and cargo aircraft. The AEW requirement was to have a radar range of 250 miles at 25,000 feet. Operational lifespan for the airframes was to be a minimum of 10 years. They were expected to be ready by late 2012.

Finally, in addition to all of this, The São Paulo's SH-3 helicopter fleet was to be replaced by six S-70B Seahawk helicopters. They were purchased in 2008, upgraded, and refurbished for delivery. The helicopters and a package of engines and support equipment were delivered in 2009.

At the end of 2010, sea trials began, and as of 2011 the São Paulo had been evaluated by the CIASA (Inspection Commission and Training Advisory). She rejoined the fleet in late 2013.

A great article about the upgrade into 2008 of the Sao Paulo can be found at the following link (you can translate that page into almost any language):

A good article about the purchase of the C-1A Traders for conversion to S-2T Turbotrackers and then into AEW, tanker, and cargo versions can be found here from late 2010:

DCNS was contracted to do further work on the Sao Paulo's forward catapult in November 2013, to check and test it, which they performed successfully in December 2013. Here's their press release about it:

At this time, after the Brazil chose the Saab Grippen as their future fighter aircraft, there is a lot of interest, and even intent, on having Sea Grippens be purchased for the carrier to either completely replace the A-4s or to compliement them. If they have a wing of up to 12 or even 18 Sea Grippens operate from the carrier with modern S-2 AEW aircraft, they will have a very potent carrier for Brazil that will give them significant experience over the next ten years until they bring onboard a new carrier that they are planning...along the lines of the DCNS PA2 design that was proposed for the French Navy but that they, to this date, have not elected to build, but which Brazil is seriously considering as a replacement for the Sao Paulo.

So it would be best to answer and open the door and talk to us when we come and knock politely during the day. Otherwise some BA momma' gonna come hammerin' the door down in the dead of night.

Now that I have that out of my system...take a look at the post before your last.

I have to say that the Brazilians have the Sao Paulo (the old French Foch) looking pretty ship shape these days.

Ingalls-Shipbuilding’s-Amphibious-Ship-America-Returns-after-Sea-Trials.jpg


World Maritime News said:
The amphibious assault ship America (LHA 6) returned to Huntington Ingalls Industries’ Ingalls Shipbuilding division Friday following successful acceptance sea trials in the Gulf of Mexico. Ingalls’ test and trials team successfully demonstrated more than 220 test events to the U.S. Navy’s board of inspection and survey (INSURV).

“It was a proud three days at sea, and America proved she is a quality ship,” said LHA 6 Program Manager George Jones. “The LHA 6 team’s tireless and diligent effort paid off as our scores from INSURV indicated. We will continue this effort over the next several weeks to have LHA 6 ready for the sailors and Marines who will man her as part of the U.S. Navy fleet.”

During acceptance trials, America performed all required sea trial evolutions, including the operation of the hybrid gas turbine/electric-drive propulsion system. Other tests included anchor handling, steering demonstration, flight deck operations, and combat systems’ evaluations.

“The Ingalls/Navy team did an outstanding job in presenting the ship to the Board of Inspection and Survey,” said Richard Schenk, Ingalls’ vice president, test and trials. “It is a tribute to all involved in proving the capabilities of such a large and complex ship.”

When America enters the fleet, she will be the flagship of an Expeditionary Strike Group, strategically positioning Marine Expeditionary Units ashore across a full spectrum of missions, including humanitarian, disaster relief, maritime security, antipiracy and other operations while providing air support for ground forces.

America-class ships are 844 feet long and 106 feet wide and displace 44,971 long tons. The gas-turbine propulsion system will drive the ships in excess of 20 knots. They will accommodate a crew of 1,059 (65 officers) and 1,687 troops. The America-class will be capable of carrying a Marine Expeditionary Unit, including Marine helicopters, MV‐22 Osprey tiltrotor aircraft and F‐35B Joint Strike Fighter aircraft.

The newest class has an increased aviation capacity to include an enlarged hangar deck, realignment and expansion of the aviation maintenance facilities, a significant increase in available stowage for parts and support equipment, and increased aviation fuel capacity.

Wow! Italian aircraft carrier Cavour (550) sailing round Africa, now at the point Italians call "Capo di Buona Speranza."
In English it is called the "Cape of Good Hope." That's a nice pic of the Cavour, clearly showing the 16 VLS cells forward.

I found this picture of a JMSDF formation today and really like it:


jmsdf-review-001.jpg


1 x Soryu Advanced AIP Conventional submarine
1 x Atago Class AEGIS DDG
1 x Hyuga Class DDH
1 x Kongo Class AEGIS DDG
1 x Takanami or Murasami Class DDG

With the readiness of the JMSDF they can easily put to see two 19DDH and actually we have seen them do it

Now with the two 22DDH they could easily put to sea atleast one 19DDH and one 22DDH

19DDH can be used to screen ASW and 22DDH can have V-22 and F35B

Escorted with the vast arsenal of Osumi Class, DDG, FFG and SSK the JMSDF will be a extremely well equipped and trained force

JMSDF camo of those giant Atago Class looks totally in class of a world class navy

I believe JMSDF will be able to field a capability and firepower of a Expeditionary Strike group in the future

Some updates on the carriers in the coming years

USS Ronald Reagan CVN-76 based in San Diego will shift to Yokosuka Japan when USS George Washington CVN-73 moves back to Newport News for a RCOH

USS Theodore Roosevelt CVN- 71 which emerged from a RCOH will then move to replace CVN-76 which will be sent to Japan

It's called a carrier swap

The new optimized fleet response plan (OFRP) will standardize the rotations and have a fixed 36 month rotation time span
