Figure 2. Trench Bunker
Ordnance Bunkers:
The ordinance is a weapon of large cannonry guns ammunitions and missile
launchers. Especially anti-ship artillery its historical actions of
protected all-embracing bunkers systems [4]. That typically
accommodated the group of squad operations of working weapons systems.
Modern days weapons systems handled in fully electronic and hydraulic
automation actions of counterattacked. Especially ammunition is prepared
is dependent upon the site of the area of the bunkers. For examples of
cold region, snow area is special ammunition weapon handled target. And
long-range seashore areas, missile (short and long-range) and long-range
air command anti-ballistic missiles, that types tactical weapons are
handled in bunkers. Ordinance cannon bunkers are mass and entity in pre
cold war bunkers. Dover strait coastal gun fixed provision in northern
France were up to 3.5 m thick and beneath the bunkers. Is mechanical
design productions for the V-3 multi charge cannon.
Types of weapons systems use in bunkers:
- Bofors gun systems
- Bantam (Rb 53)
- 0.53 calibre machine gun
- Anti-tank missile
- Internal navigation systems (INS) and (GPS)
- Defence radar systems
- Super & Hypersonic missile Systems
- Bofors guns systems:
Bofors guns are the simplest and most powerful efficiency of land, water
and air base defence power systems. Is working for autocannon designed
in 1930 Swedish defence designed and manufacturer “AB Bofors”. Its
services in 1930 to and for the most part popular weapons in currently
services in 21st century’s. its high activations in all types of wars in
WW 2, Indo- Pakisthan war conflicts, Korean, Vietnam, Gulf, south
African border, Yugoslav, Yemeni civil, Yemen wars, Yom Kippur,
Falklands, Lebanese Civil War, Saudi-led intervention in Yemen. Its
typically used inland to air, land to water base, air to a land base and
water ship base to land or air anti-aircraft attacks. Its 40 mm L/70
Bofors models are used by the ends of WW 2, tat model payload of
ammunition is automatically [5]. And the speed of attack in jet
aircraft. Its simplest Bofors gun Consequently has to long ranges higher
rate of fire. And the efficiency of the integer of rounds fired the
ended the period of rendezvous. Bofors designed updates of 40mm and
alternative to making the 57 mm designed. It is most powerful for
compared 40mm L/70. The new designed of 40mm is a larger 40 x 364R round
firing. The shell weight is less than 1Kg and velocity of muzzle firing
is 1030m/s. and rate of firing is 200 to 240 rounds/minutes [6].
Modern Bofors additional techniques to improvements of designed
developments 300 rounds/minutes (5.56 rps). BAE systems C-ITC is Swedish
acquired high-tech companies. Its includes innovators computer-based
research replication and training technologies. Bantam (Rb 53) is also a
model of Bofors missiles criteria lightweight anti-tank combating
missiles, developed in the 1950s by Bofors.
0.53 Caliber Machine Gun:
M 2 browning gun [7] is a 53 calibre heavy machine gun (.53BMG) it
designed models in world war 2, the designer name is john browning. It
designed is the same First models M1919 (BMG) Browning Machine Gun.
Which was a barrel for the 7.62mm ammunition are use M2 was more
influential 50 BMG ammunition. Its development of updates in forename of
the gun itself is standards for Browning Machine Guns. 50 calibre M2
browning machine gun is most flexibility in unarmored, and light
armoured of vehicles in coast guard boats, attacking helicopters, and
bunkers are majorly used. The 50 BMG is the late 1910s. entering by the
C.I.P ammunition developed in the browning 50 machine gun in the late of
1910s. its heavy duties for the war of during WW 2, Korean, Vietnam,
Falkland, etc. in the 2000s to 2010. Is a majorly used in the machines
in NATO countries. And current M2HB is productions in the US general
dynamics or US ordinance. Via foreign military scale. Specifications of
BMG weight is 38 to 58 kg and used tripod traverse elevation mechanics.
The total length of BMG is 1654 mm and the length of the barrel is
1143mm. 12.7x99mm NATO ammunition cartridges are fit for the gun. This
operation is short recoiling-operated. 400 to 600 round/min and 750-800
round/min(AN/M2), 1200 – 1300 round/min (AN/M3). And muzzle velocity is
890m/s. long effective firing ranges (2500m) is long-range targets. M2
or M9 links belt loading systems. M2 BMG is the same visions of M1917
BMG using every time gauge.
Anti tank missile systems:
Anti Tank Missile is an (ATGMs) Anti guidance missile weapons systems
[8]. It is designed to be primarily to hit the targets and destroyed
the heavily armed defence vehicles. ATGMs is short-range to desired to
the efficiency of long ranges. In sizes is from shoulder-launched
weapons. Which is used single-armed to soldiers or tripods fixed the
launched the tactical target ranges. It required a squat team to
transported fire, handled with air naval and land major forces. The
introduction to the contemporary battlefield. It will operate the
man-portable ATGMs. Comparing heavy with large missile systems and
Advance is the same power and comparing with large missile tripods and
similar power and compact handled ability operation systems [9]. And
defeat the light and medium tank. Older ages anti-tank infantry missile
is such as Anti-tank Rifles, anti-tank rockets (RPG, Bazooka) and
magnetic anti-tank mines. Its worked in limited range distance and
armour diffusion capability is required closed target approaches. And
modern anti-tank missile is identified the years is 2016 and used over
the 130 countries.
Types of anti-tank missiles systems:
- FGM-148 Javelin (ATM) of the US army,
- 9M133 Kornet tripod-mounted Russian ground force,
- PARS3 LR fire and Forget missile of German army’s,
- RAFs Brimstone missile
- Spikes (missile) a capable of making ground top attack flight profile
in anti-aircraft surface missile systems.
- Internal Navigation and Global Position Systems (INS, GPS):
Its use of GPS satellite signals to accurate or regulate as salvation
from an internal navigation system (INS) its application for GNSS/INS
systems [10]. The GPS/INS methods are gives is a accurately gather
free positions values that used to assigned the values of reset the
internal navigation systems blended with it used by the mathematical
algorithms, for as a Kalman filters, it is trigonometry angular compass
reading of the unit can be contingent from the series of location
latitude and longitude or Co-ordinates positions updated from the global
position systems [11]. INS/GPS systems benefits are may be
calculated by the GPS signal and that the Internal Navigations System
can provide the location point of positions and angles updates at fast
to analyze the calculation rate of that GPS for heavy impact mount
mobilization. And one plus points of GPS is some time lose the signal
and the internal navigation systems is continued to complete the task of
the intended position and deviation of angle during the period of the
lost GPS signal. INS and GPS are 2 types of systems is complementary and
worked to accurately the employed mutually. Its commonly used on
warships and aircraft and navigation purposes. Its allowed the level
positions of velocity and analyzed the calculated rate is quicker than
the GPS receiver. Its always allows for accurately calculate the
aircraft altitude its rolls, pitch yaw angles. Its usually proposes
using the extended Kalman filter (EKF) and Unscented Kalman Filter (UKF)
[12]. The UKF is required the estimating of a matrix square root of
the state error covariance matrix, used to calculate the overspread of
the sigma points for the unscented transform. That lot of ways to
determine the calculate the prevailing conditions square root. And have
been currently and compared to the GPS/INS systems application. That
works is optional to analyzed the Cholesky decomposition linear
algebraic methods. GPS and INS are automatically applied for an
autonomous navigation area. Its mobilized mount impact vehicles such as
warships, tanks, aircraft, bunkers skate slips, roll and tire cornering
stiffness estimations.
