the u.s is testing its new gigantic 13 billion dollar aircraft carrier
aircraft carriers are warships that evolved from balloon carrying wooden
vessels into nuclear-powered vessels carrying scores of fixed and rotary wing
aircraft since their introduction they have allowed naval forces to project air power
great distances without having to depend on local bases for staging aircraft operations
another giant was launched the aircraft carrier
john f kennedy which is called the aircraft carrier of the 21st century
the uss john f kennedy is the second in a series of 10 gerald r ford class ships the new aircraft
carriers will replace the nimitz-class ships that have been in service since 1975.
the ship's construction cost at least 13 billion dollars and the final cost will be even higher
in addition to airplanes the aircraft carrier is outfitted with medium-range room 162e ssm
anti-aircraft missiles ship-based anti-aircraft missiles and anti-aircraft artillery systems
all these facts attract everyone's attention so john f kennedy deserves a separate
big story so it all started when u.s secretary of the navy
ray mabus announced the next gerald r ford class aircraft carrier would be named john f kennedy
according to the u.s navy ship naming convention aircraft carriers can only be named after u.s
presidents i must say that the name john f kennedy has already been used in the name of the ship
that is an american kitty hawk class aircraft carrier in the movie 2012.
the old aircraft carrier john f kennedy was the fourth and last of the kitty hawk class
the ship served for about 40 years the ceremony of withdrawal from the fleet took place on august 1
2007. despite the fact that aircraft carriers can only be named by presidents there are exceptions
to the naming convention for the u.s navy's nimitz enterprise design of the new super carry
northrop grumman began preparations for construction
on february 25 2011 steel cutting for the new john f kennedy started on february 25th 2011.
on august 22nd 2015 construction began on the aircraft carrier keel
on april 30th 2018 a division of northrop grumman corporation huntington ingalls industries
announced that the ship was 75 complete after a year 0.5 the aircraft carrier was launched
the baptism took place on december 7th 2019. the godmother of the ship was president kennedy's
daughter caroline kennedy the launching ceremony was attended by over 20 000 people
the officials talked about the power of the american navy the super carrier's abilities are
truly amazing the giant is 1105 feet long and 256 feet wide the height of the ship reaches 250 feet
the displacement is 100 000 tons at the same time the speed excels 30 knots such a crazy thrust
is achieved by using two nuclear reactors batch tail a and b the power of each is 700 megawatts
the new generation 81b reactors operate on the same principle as reactors for land-based nuclear
power plants the only difference is that their energy is transmitted to four shafts that drive
the ship's propellers these two nuclear units are able to fully cover the electricity demand
of a half city the navigation autonomy of the aircraft carrier a's is customary their food
supplies on board will be sufficient to feed over 4 000 personnel and service personnel for 100 days
the decision increased the speed of movement of ammunition in aircraft because the area of the
takeoff deck increased there are nearly 100 aircraft in the john f kennedy air wing for
various purposes including the carrier base fighters f a 18e f super hornet and f 35c
which are perfectly suited for aircraft carrier integration with the f-35c fighters initially
the delivery of the aircraft carrier involved the two-stage skin first the basic version and
then additional equipment for integration with the f-35c fighters the concern was in pain in
addition to the aircraft carrier john f kennedy's capacity electronic countermeasures aircraft e18g
growler early warning aircraft e .2 d hawkeye and transport c to greyhound can be placed on board
as can mh-60r as helicopters and drones if necessary the electromagnetic catapults
which recall that earlier steam counterparts refused on american aircraft carrying cruisers
or the know-how of the new generation aircraft carriers which include ford and john f kennedy
as a result pilots experience less stress both physically and psychologically associated with
overload which translates into a lower risk of making a mistake during takeoff
the land has become no less comfortable as you know most aircraft accidents involving
carrier-based aircraft occur either during takeoff or landing to facilitate the landing
on the aircraft carrier john f kennedy an electro-mechanical aero finisher is used
the deck part of such devices consists of several cables stretched above the deck and connected to
trumps when landing on an aircraft carrier the aircraft has a high speed the speed is stamped as
a result of the engagement the control system uses bypass valves to constantly regulate the pressure
and fluid flow in the hydraulic braking system thanks to dissolution the aircraft decelerates
more smoothly the aero finisher can be configured to receive aircraft or different weights
this gives the prospect that john f kennedy will be able to carry six generation carrier-based
finders we have already talked about them in our other video it is noteworthy that the energy
that is generated when the landing aircraft is breaking is accumulated for further use that
is the work of the era finisher is partially provided by the energy accumulated during the
breaking of the aircraft furthermore there are no unknown mechanisms or new laws of physics
and the operation of these devices the first copy out is that the system's compact
let it be an aircraft carrier and a large ship but this is a ship where every inch of space must work
for a common goal which is the main reason for optimizing already known and reliable technologies
the second new want concerns the reliability and endurance of the catapult the electromagnetic
catapult allows one to increase the intensity of flights by up to 220 per day at peak load
for example nemitz is capable of only 120 flights a day in combat conditions the aircraft carrier
john f kennedy is almost twice as effective as the mitz-class ships neither russia nor china have
such catapulting and braking technologies that is why they are aircraft carriers admiral sendoff
and leon which belong to the same type of aircraft carrying cruiser are not capable of carrying heavy
transport aircraft and reconnaissance aircraft with a long takeoff run plea outing includes a
sufficient number of people who are far behind the aircraft carrier john f kennedy the question is
why is the u.s building new aircraft carriers each of which will cost at least 13 billion dollars
when the old and amidst class cruisers are unrivaled
it's all about the service life prior to the introduction of the first because americans hadn't
produced new aircraft carriers in over 40 years so the first minutes of all number were crucial cbn
68 entered service on may 3rd 1975. the most recent aircraft carrier george w bush entered
service in 2009 and was built using the same technology 40 years without new ships is a long
time in terms of technology continuity if you do not build new aircraft carriers for a long time
and you get to that point when the existing technologies become very outdated
the emergence of effective means of destruction of floating airfields that the russian and now
chinese armies have cannot be ignored aircraft carriers have become more vulnerable and using
them to maintain world dominance has become more difficult in addition active american emits class
aircraft carriers are often idle at the world's largest naval base in norfolk the reason for the
downtime is technical malfunctions in short the appearance of john f kennedy is entirely justified
furthermore if you count the construction time of an aircraft carrier the northrop grumman
corporation division needs to accelerate and release aircraft carriers faster
we will monitor the development of the situation including the emergence of
systems that are capable of withstanding the hypersonic missiles of russia and china after
all it's the hypersonic missiles that pose the greatest danger to the larger ships in the world
