Military Parades: Portugal - Part Two

Portuguese Marines, Comandos, Paratroopers and special forces (like UPF from Portuguese air Force or Rangers from the Army) are known by their efficiency in battle and peace missions but also by the piece of art that they do in military parades. Of course the main gear and vehicles are important,  speacially in a situation were the forces are seen by the public, but also the songs and motto are impressive for the population who see them march. Let's take a breve look:

Military Parades: Portugal

Portugal, one of the most old nations in the world with more than 874 years of history (if we begin with Zamora document between Portugal and Castela, today Spain), have a rich military history with VII centuries in the Navy and a much older Army (was created in the XII century). We had so many wars, most of them with Spain, but also in Asia, Africa and South America.  In the last century, we fight in WWI and Africa Colonies, after that we went to Kosovo, Afghanistan and back to Africa again. And of course there's the domestic missions like SAR and Patrol our Economic Naval Area (or EEZ - Economic Exclusiv Zone). 
But he have a problem with history. Much of the material end in scrapp, or abroad, with one significant part in the top of a air base, waiting recovery. Even in film and video there's not much things recorded, but in military paredes, this is what i have find in youtube:

When Royal Navy had two good carriers: Audacious class review in a past and present english navy


Audacious class carriers were the last convencional aircraft carriers class in the Royal Navy. After Ark Royal end in 1980, his substitutes had no catapult, angular deck or stop cables, so only operate helicopters and VTOL/STOL fighters. Why? Much more cheap. The problems: A very limited type of aircraft that can be use (only F35B and Harrier, probably one or another STOLV could be adapted to operate but there are not many). In combat the concept prove to be not so good, and US Navy give to their LHA more size (in hangar and deck fly, from Tarawa to WASP) and Royal Navy done is one aproach; the Queen Elisabeth class with two ships. 
If we see the operation carriers in RN after WWII it is evident that most of them were in use more than three decades and were modified several times, to a angular deck, to jets and in the final state to operate the VTOL planes (see HMS Hermes), so the investment was secure. With PA76 and Malta Class canceled the Ilustrious, Invencible and Ark Royal (VTOL) were only an unleash, but after the insatisfaction due to their size and limited operations, at least the logic was to make a similar projecto to russian Kuznetzov. But instead were made an "hercules" with few options. The reason? If we see the Audacious class and their operations, the only reason is money and a bad planification (pray for F35B to be a good fighter or... ups, no options).  Even so, the fund problems is so big in RN that the carrier fleet and his future is not certain  (there's a chance of HMS Prince of Wales go direct to reserve). And the operations, with Daring class heat problems and without SSM (the RN is studing a way tho have harpoon plus 2018, after they said that were retired), it's unknown. 


Fig. 1 - The 2 new british carriers to Royal Navy. Prince of Wales and Queen Elisabeth are 70 000 tones giants, but without catapults and arrested cables, are less funcional than 36 800 t Audacious Class.  Can operate only VTOL fighters and helicopters. The french carrier Charles de Gaulle is smaller and can operate all types of naval planes.
HMS Eagle introduce the angular deck, a british invention that made operations in the carrier much more easy and secure (but only three years after beein comissioned the change was made). The parking area in front of the supertruture was now secure to park because the planes land in a track, were if they miss the stop cables, only had to climb up again (one of many, like the land system of lights and mirror, etc). Jets were less manobrables in low altitude and speed, so the  size of the carrier to put an angular deck was important (the short ones were used as command ships or helicopters carriers, but in other navy's like Australia, Canada, Brasil Netherland or Brasil, small carriers used the angular deck with jets like the A4 Skyhawk).
Both carriers were big enought for refit after refit, but Ark Royal was the main investiment (even the more old HMS Victorious had a more substancial reconstruction, to be put out of service at same time than Eagle https://en.wikipedia.org/wiki/HMS_Victorious_(R38) ). The result was that the main fighter was Sea Vixen, with Phantom II only in Ark Royal and used a par of times in is colege class. And when Royal Navy was pushed to finish conventional aircraft carriers, Eagle give the spares to Ark Royal (from 1972 to 1979), to keep some aerial capacity (the Invencible class were in construction).
The three Ivincible class carriers were ASW cruisers with a deck and hangar, that had been adapted to operate Harrier VTOL Fighter, but only 5 (original was only for helicopters), wich give some protection to the helicopters or the fleet, in a sort of missions to be made in North Atlantic, especially to fight soviet submarines and recon planes (main task of defence and surface attack were made by the american fleet carriers), but in more high protection or attack missions to the continent, british used RAF units (wich had also the Harrier in a attack version with FLIR on the nose). 


Fig. 2 Audacious class carriers were Eagle (more close) and Ark Royal (far away). 

And when Falklands War beggin, from the old carriers only the rusty Hermes was operational (was the main carrier in South Atlantic because HMS Invencible was much smaller), and in battle several problems were pointed in the new carrier, like the little hangar or the few space in deck to park fighters and helicopters. Their armament was also a problem, especially the lack of a CIWS to destroy missiles like the exocet, but also the Sea Dart system (who sometimes had to rebut computer weapon's, with a lost of time in that restarted who enable the launcher to use de missile). The worst was that there were no AEW, and when the carriers escape with some luck to argentines fighters and exocet missiles (other units like HMS Sheffild had no such luck), the navy see the serious mistake. 
Up to all this, there was only in that time two carriers avaible for South Atlantic, with emergency work in HMS Bulwark (sister ship of Hermes from Centaur class) and an offer from United States to use one of the Iwo Jima class Helicopter Carrier, if necessary. Was no nead, but the price in other Royal Navy and civilian ships, was hight.
Also the plane to sell one of the Ilustrious Class carriers to Australia was cancel, and Royal Navy keep all them for more two decades. Also the plans to end carriers in the fleet or made them like a variation of Ilustrious were canceled, with the CVA1 and 2, being used was a model for the diferent but much bigger CVF. But if Queen Elizabeth is much bigger and complete than Illustious, without an angle deck and stop cables, will be used only by VTOL planes, what is for me a limitation in a 65 000 t carrier, at least if with F35B don´t came also Osprey AEW and CDO/Carrier on board (Lightning VTOL have less fuel than the A and C versions). The rest, is the internal RN budget problem, that we have to see were it takes the fleet, also in the carriers and his air wing.

HMS Ark Royal

Fig. 4 - By his airwing (Wyvern's and Sea Dart), it is a photo of 1955-58.
The comission was in 1955, with Ark Royal been one of the last build carriers in England, besides the design and construction beggin in World War II. After all the carriers from WWII went out of service, Ark Royal was the main one in the 70's, with is partner HMS Eagle, that had a minor refited, even when PA76 were canceled.
In the bigining the carrier operate with a mix of helicopters like the Wirlwind, turbo prop Wyverns and Sea Hawk jets, than in the 60's came the Phantom II and AEW (first Skyraiders and then Gannet). Some changes made to operate the F4 in a carrier much "short" than the americans and with central elevators, but was not a problem use 40 aeroplanes in that ship, even the hangars were much more lower (british continue to make separete hangars in level 1 and 2, after the war, when americans prefere enlarge the main one).
But since the 60's an orgie of cuts and more cuts in the navy budget reduce the fleet and no new carriers were made, so by the early 70's only Ark Royal were in service, with all the ones from WWII put out of order (HMS Hermes was converted to a STOL/VTOL carrier). But in 1979 the last  CATOBAR survivor was discomissioned, and Phantom II, Buccanear and helicopters were to RAF (Gannet was to junk, and latter the navy will miss him badly).
Off course when Falklands war was started in 1982, Eagle and Ark Royal, were missed, specially by the fails of the carriers fleet (AEW was the major problem with Sea King AEW who resolve the problem only entered in service after 1982 war).

Fig.5 - Hangar of HMS Ark Royal with Buccanear, Phantom , Wessex helicopter and a AEW Gannet. Picture taken from elevator (note the two stages hangar). 
Operations in Ark Royal were easy by the 60's and 70's padroms. With F4 or Buccanear, a much larger plane the elevators and two hangar need some technic to operate, like radar radom rotate to left and air brake  open, before get to deck fly.  The use of internal elevators were other of the british pré World War ideas that they never abandon t'ill the Queen Elisabeth class in this century (Eagle was completed with an elevator at the end of the angular deck, but was remove), what gives less space in hangar and enable the use in landing and take off periods.
The carrier operate about 40 planes and helicopters, and in some ocasions the american F4 from Us Navy and Marines were used in total operations from the deck with no problems (http://www.eacott.com.au/gallery/d/1694-/US+Marine+Phantom+RN+colours+06+onto+waist+cat.jpg and with US Navy F4 from carrier USS Independence  https://s-media-cache-ak0.pinimg.com/originals/1b/b4/de/1bb4de55801ec2f27011d387760165c4.jpg ). Also the british F4 were comum seen in american carriers, except the small ones from Essex class (they operate as ASW submarines or in a atack role with the A4.
Original steam catapults (first ship to have them before launch) were able to launch original 14 000 kg airplanes but the refit of 1967/70 give him a more powerful catapults and heavy jet blast deflectors to operate Phantom an Buccanear Mk2 (amount others upgrades). But is sister ship was not had this type of upgrade so came less powerfull besides being identical and could make almost the same if refit to do so.

Fig. 6- Ark Royal in is final operational stage. The Seacat missiles launchers were never installed longbow and starbow.
One of the four Audacious, Ark Royal was an WWII order (1942), but only launch in 1950 and completed five years later. The 5.5º angled deck and the miror landing system were the most significant innovations, that make the carrier capable of launch and recovered planes at the same time. After comission, the port 110mm guns were removed and 4 years latter all of them were out to improved angle deck operations, but after 1970 even the 4.5 inch guns were retired (the seacat missiles to replace them were never instaled, so from the inicial 70´s to 1979 there was no defensive armament in the carrier).
Seacat was still in service with some RN units in 1982 but were retired in most of them by the late 80's. In fact by that time was Sea Wolf a good short range AA missile, but if needed Stinger or Blowpipe could be used in visual defence. French navy used also the Mistal in a twin repair or the automatic Simbad system, similar to the one with Stinger missiles in service by the US Navy small ships.  
Indian Navy make it a diferent aproach with the AA missile Barak in VLS conteiners, in several ships. like the Ex Hermes, that was used t'ill  last year (a historic society want to make a museum from the ancient carrier). Anyway, the old carrier was much more used than all the others in RN, such has been in service from 1959 (was launch as a CATOBAR carrier, and with the Harrier converted to operate the type), to 1984 with the british and than with India from 1987 to 2017, in a total of 55 years in active service.
Today ESSM is an excelent choise to a AA missile about 50km range, like we can see in the Perry frigates (who had original only the Standard missile, and receive a VLS), or in the ships with Sea Sparrow in the original 8 cannaster laucher, since the upgrade is sensors, missiles and software. So, has we see, even a old Ark Royal could have a letal AA system, if was in service in this days, but also guns like the Phalanx 20mm, Goalkepper 30mm or bofors 40 mm. It as all a question of choise if the main body of the carrier were in good conditions.


Fig.7  - F4K Fg1 Phantom II is launch by longbow catapult.

The lack of investement in RN surface fleet and the constant reduction from for example budget to carriers (the RN see the strategic Polaris missiles go to their nuclear expensive submarines), leaves no sucess to another CATOBAR carrier, and even the problems with minor units like frigates (for exemple Type 21),  or auxiliary ships, leave death and destruction in the Faklands war. One of the reasons was that new VTOL/STOL carriers had no AEW (the Sea King AEW was done after the was, specially because the Falklads bad and tramatic experiênce  http://www.airforce-technology.com/projects/seaking/seaking7.html ). 
Probably HMS Ark Royal, if in 1982 was in service, Agentina had not invade the Falklands. But the few investiment and the service of two minor aircraft carriers (HMS Invencible and HMS Hermes, who was near the end of service), plus the retired of HMS Interpid from South Atlantic waters, leave the "Junta Militar Argentina", to tink that british no reply (military speaking) to the invasion of the almost lost Islands (the original plan was to make a symbolic ocupation an leave Malvinas/Falklands, but the union of the people about this cause make the plan go around). Today, reach in oil, natural gas and also fish, are reasons enought to have the Falklands with a significant military presence (with probably the new carriers to go regular in South Atlantic waters).
The return of a more powerfull classe of carriers (not CATOBAR, but close enought), is the result of the need of Royal Navy by the XX century end and the beggining of first to decades of XXI, assuming that the ancient class were short and with limitations. But even Invencible class and Sea Harrier had a few use in Royal Navy, since the last upgrades, with again the budget and the debit of millions, being the invisible enemy of the fleet. 
Fig.8 - Typical photo from late 70's from HMS Ark Royal.  
True that Ark Royal had limitations, by deck, hangar, catapult (and of course, age), but if we compare to the Clemenceau or Foch french carriers, they used a more powerfull fighter and attack aircraft and had specific AEW (Aeronavale used the ASW Alizé to make some service in this area, but the major function was to fight submarines). Yes, this carriers were not the best example, since ex Foch (now NAE S. Paulo), was put out of service by motor and generator problems (Clemenceau was out since De Gaulle carrier was in service), but the main reason is that there's no money to make the modifications and keep the carrier with Brazilian Navy.
NAE Minas Gerais was in service since 1944, descomissioned only in 2001, were still in very good conditions (the main problem was that is motors only made 25 knots and the deck space /catapults were limited to planes like A4 Skyhawk. Even so, this one upgrade by Embraer, his a good fighter /attack aircraft, with BVR missiles and guide weapons). The "problem" with the speed that was always the main reason for the end of service, it is a strange reason since that for example since "Bahia" or "Garcia de Avila" are not faster (they do about 21/17 knots), and USA planned use their LHA that have similar speed in low or medium danger areas.

HMS EAGLE

Fig. 15 - HMS Eagle after recived is angular deck. The Carrier had a little tonelage superior to HMS Ark Royal, but was less used and had minor upgrades. 
HMS Eagle was the second carrier of the class put in service (all the rest were canceled), but always be treated by Royal Navy and British Defence like the "ugly duck", with limitied upgrades and minor investement.
The carrier never used permanetly the F4 Phantom II and had less space to parking and operate is air wing, so Sea Vixen was the main fighter t'ill the end of the aeroplane and carrier in 1972. With the Royal Navy lack of funds to a real Carrier to substitute Eagle and Ark Royal, first one was retired for give pieces and spares to unique ship with planes in service.
It's true that the basic problem was money, but are strange options in the Royal Navy, and it's important that the common defence reader understand options and the budget of them: Was more chip the development of Sea Harrier and the 3 ligh carriers of Invencible class, than one substitute to Ark Royal or to keep him and Eagle with upgrades t'ill Queen Elisabeth?
Lets see: RN have an average ou 30 millions (pounds) by upgrade, and if we are talking about the 2 carriers most likely numbers between 60 milions and 100 millions. A new ship it is much more expensive (new light frigate is about 190 millions, with normal ones and destroyers up to 600 millions), and if we are talking about a carrier the price is much higher.
The same for planes and helicopters, since RN only have the Merlim, but Sea King AEW is in the end of his live. So, they nead to buy the F35B, developed the Merlim AEW and pray for no more cuts in the budget.  

Fig.16 - The Hangar of Eagle configurated to a party, in Malta.

Then there's the planes and helicopters question. Phanton, Buccanear and Gnat were all develloped, but when RN manage the ASW Carrier, there was no Sea Harrier. And after Falklands, Sea King AEW was in service, exactly because the losses of the war.
In Gulf War Buccanear and Phantom were still there, what in means that Eagle less used than Ark Royal was possible to be on service. Not that RAF with the Tornado  or Jaguar could do attack and defense without problems, but RN with a Phantom II was a much more accurate presence than the Royal Marines.
The French used the Crusader in the Clemanceau carriers to the beggin of the XXI century, a fighter with less capacity to make a upgrade then the F4, wich in the land version is in 2017 use by 5 nations like Japan or  South Korea. The Helenic and German Phantoms used the AIM 120 missile what gives BVR capacity to the old fighter, with also attack missions beeing made with guide missiles and bombs like AGM65 or Paveway. Of course the state of the fighter "main body" is the ultimate key to a long service or an extense upgrade, but with 5 195 produce, many still in use (Qf4 was used t'ill 2016),  and a big reserve of spares, probably Phantom in RN was a possible realitty to this days. 
HMS Eagle less used than HMS Ark Royal, probably would make if it the significant upgrades, also Bosnia and again Iraq in the XXI century. A fiction view but a more powerfull one than RN participation with  missiles from submarins and frigates or destroyers in the surface role. And if the new class of carriers named Queen Elizabeth was to much people the raise of Royal Navy with is power to have a powerfull strike group in the sea (like in the 60's and 70's), the problems with budget, F35B and the nead to sell LPD, is a significant punch in the face. 


Fig.17 - Due to the lack of upgrades that HMS Ark Royal had, the principal fighter of Eagle was always Sea Vixen. 


CONCLUSION

Royal Navy was probably the carrier fleet in WWII that most principal ships lost (the Imperial Japonese Navy had more carriers sunk, but his post war fleet doesn't have them because the constitution from Japan prohibited), but emerge from this war with a major and powerfull carrier fleet.
But from this time to current days, all  was a mess and still his. It is true that people was tired from war, and money was nead in other areas than military, but in 1950 was Korea, in 1956 Suez, in 1960 Burneu, etc, etc. Also the need for nuclear weapons that after the V bombers were put in the submarines, armed with Polaris missiles, and the budget for other ships was year after year little. Principal result is that the carrier fleet had less money and some units were sell to Australia, Canada, Brasil, Argentina, India and Netherlands (most of them were put with angle deck and Argentina for example operate A4 and Super Etendart atack fighters to the 80's). The units that were keep in Royal Navy only one small part had a decent upgrade (Royal Navy only used piston fighters in Korea, bacause of the carriers), and with some exceptions like HMS Victory, the budget was concentrade in the carriers made after the war (most of them projected in WWII or even launch after were put "in limbo", again by budget problems but also tecnical situations).

Jet fighters x carriers was a complicated process and Royal Navy only after Korean War introduce the type (Us Navy used F2 Phanter from the deck of their carriers), and in the conflit fight with piston engines planes like the Fury (shootdown two Mig15) and the Sea Fire. The naval fighters were slow to take the lead but with Vixen and Bucannear the main task of deffending the fleet and atack surface targets was taking care. But with the much more capable F4 Phantom II came the necessary upgrades that only HMS Ark Royal had (but with no AA Guns), with Eagle being strike in the 70's and no Pa76 (  https://www.sinodefenceforum.com/aircraft-carriers-ii-closed-to-posting.t3125/page-216 ), the death of naval fighters in RN was in process.
True that Invencible class with Sea Harrier was something, but Falklands said that was far away of being a funcional success, with heavy casualties in the fleet and short space for air wing, in deck and hangar. But the main problem was no AEW, and that situation only after the war was resolved. 
If the limitations of the Invencible class was at sight, the correction was not possible in all the situations, and the need for CIWS Phalanx against missiles, give to the carrier less space on deck. Also with new Harrier Plus the hangar was in the limit and if in there was not much to do, RN made some modifications on deck, in the sky jump area.  Again came the budget cuts, with harriers being scrapt and ships being sold or terminated, before HMS Queen Elisabeth were on service.


                                                                     Fig. 18 -  Harrier Gr mk 1 tested in HMS Eagle. 

With no fighters, and without F35B because of a bunch of problems that make all the process late, and more and more expansive, came more budget problems, with the main reason being the poor plane for the fleet (expensive ships, with less missions that the partners from other navy's or a carrier of 65 000t only for one type or fighter and helicopters, are only a few examples of a Royal Navy without a long range plan). Was Queen Elisabeth still on the fabrication process when governement sources see the F35B problems, and of couse was late to make from the carier a CATOBAR ship (too expensive), so again let's make more cuts. The one to had no SSM missiles with Harpoon being termineted in 2018 was to ridiculous to pass, but ships for sold and scrap, like the LPD and MCM, were no problems for Navy manegement and to politicians. Less F35B for RN and RAF are also possible, but   
So, make sense a fleet with two Carriers but without LPD's to project force (royal marines are in a cuting process also)? For me no, but i'm not british. My vision of a fleet is a 65 000 t CATOBAR carrier, with AEW, fighters and attack planes secure by ASW from at least helicopters. If is too expensive a carrier, we have the LHA like America Class or Juan Carlos, with Harrier fighter´s, helicopters and a force of marines that can go to the beach by a Craft or a Helicopter. Some LPD's with hangar and heavy helicopters, secure by destroyers and frigates that can fight all the enemy's. But Royal Navy had and have another way of thinking.
Like the River Class OPV, United Kingdom was a long tradition in naval construction so one of the main reasons for sell ships after one or two decades in use is to keep jobs, investement and a high number of constructions in a way to have an industry with potencial of getting a high number of orders (much of the times is the own country who makes the orders or give the money to the builder). But not all are good, with for example Type 45 problems (the asw weapon is the helicopter, there's no asw torpedos and motor only with low temperatures), and with a good plane industry, not only british have give up from Harrier but also made a carrier only for the F35 american fighter.
Logic was HMS Ark Royal /Eagle in full service with a CATOBAR substitute in the 90's or at the XXI century. Invencible class a mistake (at least like italian carrier Caio Dullio), and Queen Elizabeth an interrogation. French had Clemenceau by de Gaulle, russia the Kiev by Kuznetzov, but british have two 65 000t monster only to helicopters and a type of fighter. A short view, a internal budget problem and a risk that doesn't make sense, when a CATOBAR or a LHA are more flexible in air wing and mission.  And if two are a money problem, one is better than nothing and a garantie to a more certain existance (the two logic his one in repair and other in use), in a century were a plan with aerial re-fueling is in a metter of hours in the other side of the world. But the decision is made, so let´s see how Royal Navy deal with the carriers, F35 and a budget that is short year after year (in half a century, the future with no carrier, a better Queen Elisabeth or the CATOBAR return wil be decide by the actual class).
