The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

The ''Queen Elizabeth'' Class aircraft carriers ..[ 4296 ]

Thales - Queen Elizabeth Class Aircraft Carriers Simulation 


The Queen Elizabeth Class aircraft carriers will be the biggest and most powerful surface warships ever constructed for the Royal Navy and will represent a step change in capability, enabling the delivery of increased strategic effect and influence around the world.

The Queen Elizabeth Class will be utilised by all three sectors of the UK Armed Forces and will provide eight acres of sovereign territory which can be deployed around the world. Both ships will be versatile enough to be used for operations ranging from supporting war efforts to providing humanitarian aid and disaster relief.

Delivery

With its complement of embarked aircraft the QE Class will be the centre piece of Britain's military capability in circumstances where we cannot, or do not wish to base our aircraft on land. The ships will act as a rapidly deployable sovereign base to deliver expeditionary air operations at a time and place of the UK's choosing, but will also be highly capable and versatile vessels which will deliver a high profile and coercive presence worldwide to support peace-keeping, conflict prevention and other strategic aims.

Design
The HMS Queen Elizabeth and HMS Prince of Wales will have increased survivability as a result of the separation and distribution of power generation machinery throughout each ship. The class has been designed with twin islands, which separates the running of the ship from the flying operations resulting in greater visibility of flying operations. 
The Highly Mechanised Weapon Handling System enables a streamlined crew to operate a vessel much larger than the carrier which it replaces, meaning that each ship will have a total crew of 679, only increasing to the full complement of 1,600 when the air elements are embarked.

Affordability of through life support has also been a key driver in adopting a commercial design. Key operational spaces can be readily reconfigured and additional equipment inserted in a cost effective and timely manner to suit the future requirements of the Armed Forces and the nation.

The ships will use an electric propulsion system that enables the prime movers to operate more efficiently and therefore burn less fuel, saving running costs.

Crew Facilities

There will be four galleys on board and four large dining areas which will be manned by 67 catering staff. The largest dining room has the capacity to serve 960 crew members in one hour.

Each ship will have an eight bed medical suite, operating theatre and dental surgery, which will be managed by 11 medical staff. These facilities can also be augmented to suit the requirements of every individual mission.

Crew facilities on board both ships will include a cinema and fitness suites in order to provide crew members, some of whom will be away from home for months at a time, a good range of recreational activities. Crew members will have personal access to e-mail and the internet (when satellite communications equipment is not being used for operational purposes!).

Mission Systems

The ships will each have a fully integrated command system, which has three functional areas:

Information System --
 The computing hardware, internal Networks and C4I software applications to support effective command and control on the carrier. E.g. -- Considerable work has been done with Royal Navy and Royal Air Force Information Defence Lines of Development to understand how the data repository on board will be accessed by new and legacy systems and how that repository will be configured in the future.

Communications -- 
The communications equipment to support the required voice and data services. E.g. -- an emulation of the Communication Control Management System and the Tactical C2 Voice system have been procured to exercise the business process of configuring the carrier for internal and external communications.

Air Management and Protection System --
 The on-board sensor and weapon systems for the management of aircraft in the air and on deck and the defence of the ship.
