            1
00:00:00,000 --> 00:00:10,200
There are different bunker buster bombs of different caliber, but what sets it apart from the rest is this GBU-57, which is typically delivered by the B-2 Spirit Stealth Bomber.

2
00:00:10,800 --> 00:00:16,800
Due to the bomb's large size and weight, the aircraft can carry only two of these weapons in its bomb bay compartments.

3
00:00:17,820 --> 00:00:27,220
While it lacks thrusters, the weapon is equipped with four active lattice fins and a precision guidance system that enables it to glide accurately to its target using military-grade GPS.

4
00:00:27,220 --> 00:00:38,360
Constructed from a specially designed high-performance steel alloy, using its weight when falling under gravity to penetrate or dig itself up to 200 feet of underground soil or concrete.

5
00:00:39,020 --> 00:00:47,380
We'll also look into the difference between the massive ordnance penetrator and the mother of all bombs with step-by-step process of how they work, all in the video ahead.

6
00:00:48,880 --> 00:00:55,380
To give you an idea of the varying levels of penetration capability among different bunker buster bombs, let's compare a few examples.

7
00:00:55,380 --> 00:01:03,420
First, we have the BLU-109, also pronounced blue. It is a 2000-pound or bomb developed in the 1970s.

8
00:01:04,360 --> 00:01:10,900
This weapon is capable of penetrating approximately 1.8 meters, or about 5 feet, of reinforced concrete.

9
00:01:12,400 --> 00:01:17,360
Next, we move on to the GBU-28, which is equipped with a laser-guided system at its front.

10
00:01:17,360 --> 00:01:24,740
This bomb can penetrate to a depth of nearly 6 meters, equivalent to roughly 20 feet, which is as tall as a two-story building.

11
00:01:26,360 --> 00:01:33,380
However, neither of these compares to the massive capabilities of the GBU-57, also known as the Massive Ordnance Penetrator.

12
00:01:34,040 --> 00:01:37,600
It can penetrate over 60 meters into the ground, around 200 feet.

13
00:01:37,600 --> 00:01:43,700
To put that in perspective, this depth is comparable to the height of a 20-story building, depending on the four heights.

14
00:01:44,360 --> 00:01:50,500
These examples demonstrate the significant advancements and differences in penetration levels among these specialized weapons.

15
00:01:52,500 --> 00:02:01,000
Let's put an average human here against this weapon, which is 20.5 feet long, giving it a streamlined, aerodynamic shape that is crucial for stability and precision.

16
00:02:01,000 --> 00:02:09,880
With a diameter of 31.5 inches and weighing an incredible 30,000 pounds, translating to approximately 14,000 kilograms,

17
00:02:10,740 --> 00:02:15,160
it utilizes its massive weight to generate the kinetic energy required for deep penetration.

18
00:02:15,760 --> 00:02:21,200
This heavy, compact design enables it to break through over 200 feet of reinforced concrete,

19
00:02:21,480 --> 00:02:24,560
making it one of the most effective bunker-busting munitions in the world.

20
00:02:25,780 --> 00:02:27,680
Let's take a look at the parts of this weapon.

21
00:02:27,680 --> 00:02:33,980
The most important part is the body casing, made of hardened ferro-cobot alloy to withstand impact.

22
00:02:35,600 --> 00:02:39,780
Interestingly, the body comprises more than 80% of the bomb's total weight.

23
00:02:40,760 --> 00:02:43,280
Inside this cover, you will find the following components.

24
00:02:43,940 --> 00:02:47,660
At the front is the nose-fuse well, all of which are joined by a fused conduit.

25
00:02:48,960 --> 00:02:53,000
Standwitched within this rod is the explosive-filled 5,000-pound warhead,

26
00:02:53,000 --> 00:02:57,420
which translates to approximately 2,267 kilograms.

27
00:03:00,040 --> 00:03:06,640
This conduit then connects to a tail fuse, which, interestingly, is the main detonator and is crucial for delayed action.

28
00:03:08,720 --> 00:03:13,360
Moving to the back nestled inside the tail, we discover the intricacies of its guidance system.

29
00:03:13,360 --> 00:03:19,220
Here, the inertial guidance kit collaborates seamlessly with a military-grade global positioning unit,

30
00:03:19,640 --> 00:03:22,420
ensuring precise navigation towards its intended target.

31
00:03:23,200 --> 00:03:25,840
Alongside these components, one can find the adapter ring,

32
00:03:26,080 --> 00:03:28,620
which facilitates the attachment of the telemetry antenna,

33
00:03:29,180 --> 00:03:32,480
crucial for transmitting data, as well as the encryption key battery,

34
00:03:32,840 --> 00:03:35,100
which safeguards sensitive information.

35
00:03:35,100 --> 00:03:38,200
Venturing deeper into its structure,

36
00:03:38,640 --> 00:03:41,620
we encounter the thermal batteries vital for powering the system

37
00:03:41,620 --> 00:03:46,900
and the composite fins strategically positioned to aid in directing the missile towards its objective.

38
00:03:47,640 --> 00:03:50,560
These fins, meticulously controlled by internal gears,

39
00:03:50,800 --> 00:03:54,900
maneuver with precision, responding to commands to adjust the trajectory accurately.

40
00:03:55,340 --> 00:03:58,280
Let's take a look at the smaller bunker buster and how it works.

41
00:03:58,560 --> 00:04:02,200
It has a laser sensor at the front, and just behind that are adjustable fins.

42
00:04:02,200 --> 00:04:07,540
In the midsection, there is a warhead that weighs approximately 650 pounds,

43
00:04:07,640 --> 00:04:09,140
containing tritonal explosive.

44
00:04:09,800 --> 00:04:13,500
This is a mixture of 80% TNT and 20% aluminum powder.

45
00:04:14,720 --> 00:04:17,160
Finally, we have the retractable fins at the rear.

46
00:04:17,800 --> 00:04:21,220
To give you a better sense of its size, comparing it to a person can be helpful.

47
00:04:21,960 --> 00:04:26,480
The casing has a length of approximately 19 feet long, which translates to around 5 meter.

48
00:04:26,480 --> 00:04:30,440
This section is made of an artillery barrel, which is very strong,

49
00:04:30,800 --> 00:04:35,720
and has a diameter of 14.5 inches, which translates to around 37 centimeters,

50
00:04:36,240 --> 00:04:37,580
making it relatively narrow.

51
00:04:38,780 --> 00:04:41,960
They intentionally made the smaller, cross-sectional area.

52
00:04:43,260 --> 00:04:46,920
This means the bomb displaces less material, whether earth or concrete,

53
00:04:47,140 --> 00:04:50,000
as it penetrates layers of reinforced bunkers or building.

54
00:04:50,420 --> 00:04:53,640
The smaller, cross-section allows it to enter deep into buildings,

55
00:04:53,640 --> 00:04:55,860
potentially avoiding steel and concrete.

56
00:04:56,360 --> 00:04:58,940
Let's move back to the MOP and its cost factor.

57
00:04:59,520 --> 00:05:05,040
The development cost of the GBU-57 is estimated to be between $400 and $500 million,

58
00:05:05,660 --> 00:05:09,160
with its production price per unit around $3.5 million.

59
00:05:10,420 --> 00:05:13,780
Meanwhile, the GBU-28, a 4,000-pound bomb,

60
00:05:14,180 --> 00:05:18,740
costs approximately $100,000 to $150,000 per unit.

61
00:05:18,740 --> 00:05:27,460
While the per-unit cost of the BLU-109 is approximately $25,000 to $84,000 for each JDAM kit.

62
00:05:30,340 --> 00:05:32,060
Let's take a look at how this works.

63
00:05:32,640 --> 00:05:33,100
Step 1.

64
00:05:33,340 --> 00:05:35,800
The bomb deployment platform, as previously mentioned,

65
00:05:35,960 --> 00:05:39,060
a B-2 stealth bomber flies at a very high altitude.

66
00:05:40,480 --> 00:05:42,960
When the aircraft reaches the designated location,

67
00:05:43,160 --> 00:05:45,600
and the conditions are optimal, it releases the weapon.

68
00:05:45,600 --> 00:05:48,920
The bomb is designed for precision,

69
00:05:49,380 --> 00:05:52,840
and the deployment height plays a crucial role in its trajectory and effectiveness.

70
00:05:53,920 --> 00:05:56,140
Then step 2 comes the targeting precision.

71
00:05:56,820 --> 00:05:59,400
The bomb is outfitted with advanced guidance technology,

72
00:05:59,740 --> 00:06:02,500
including GPS and inertial navigation systems,

73
00:06:02,880 --> 00:06:04,400
which are military-grade satellites.

74
00:06:05,800 --> 00:06:08,680
Then comes step 3 that is adjusting the trajectory.

75
00:06:09,500 --> 00:06:11,840
The guidance information and data is then transmitted

76
00:06:11,840 --> 00:06:15,500
to the bomb's four-lattice motor's fins located at the rear.

77
00:06:16,720 --> 00:06:18,980
These fins can move and adjust in real time,

78
00:06:19,120 --> 00:06:23,020
allowing the bomb to correct its course as it descends under the force of gravity.

79
00:06:24,260 --> 00:06:27,080
These adjustments are essential because the weapon does not have

80
00:06:27,080 --> 00:06:28,640
thrusters to change its trajectory.

81
00:06:29,480 --> 00:06:31,460
Instead, it relies on the movement of these fins

82
00:06:31,460 --> 00:06:34,040
and the high-altitude drop to control its flight path.

83
00:06:34,040 --> 00:06:38,760
This is why the bomb must be deployed from a very high altitude

84
00:06:38,760 --> 00:06:42,780
so it has enough time and distance to adjust its trajectory accurately.

85
00:06:44,180 --> 00:06:46,660
Here comes the most difficult part that is step 4,

86
00:06:47,040 --> 00:06:48,280
impact and penetration.

87
00:06:48,980 --> 00:06:51,500
The bomb, known as the Massive Ordnance Penetrator,

88
00:06:52,060 --> 00:06:55,960
weighs approximately 30,000 pounds, which is around 14,000 kilograms.

89
00:06:57,400 --> 00:07:00,220
When it reaches its target, it strikes with immense force,

90
00:07:00,420 --> 00:07:03,720
designed to penetrate deep into hardened structures, such as bunkers.

91
00:07:04,040 --> 00:07:08,540
The energy upon impact allows the bomb to bury itself over 200 feet

92
00:07:08,540 --> 00:07:10,080
into reinforced concrete,

93
00:07:10,320 --> 00:07:14,980
ensuring it delivers its payload precisely where it is intended for maximum effect.

94
00:07:16,340 --> 00:07:19,400
Finally, step 5 involves the tricky part of arming the weapon.

95
00:07:19,960 --> 00:07:22,020
It was installed with two SDB fuses.

96
00:07:22,600 --> 00:07:24,340
Double fuses are required as a backup.

97
00:07:25,020 --> 00:07:28,360
The first is for G-sensing, and the second is the time-delay fuse.

98
00:07:29,000 --> 00:07:30,420
Why the redesign was necessary,

99
00:07:30,420 --> 00:07:33,060
it was to ensure that the bomb could strike facilities

100
00:07:33,060 --> 00:07:35,700
buried beneath significant layers of hardened material.

101
00:07:36,480 --> 00:07:38,980
For this reason, the fuses are placed at the rear of the bomb

102
00:07:38,980 --> 00:07:40,340
to prevent them from being damaged.

103
00:07:41,520 --> 00:07:45,460
Once the time-delay or the G-sensing fuse reaches its destination,

104
00:07:46,160 --> 00:07:47,940
it can blow up creating a mini-earthquake

105
00:07:47,940 --> 00:07:50,840
that can bury bunkers in 20-story buildings inside them.

106
00:07:50,840 --> 00:07:55,820
Many people often confuse the Massive Ordnance Penetrator MOP

107
00:07:55,820 --> 00:07:58,900
with the mother of all bombs MOAB,

108
00:07:59,540 --> 00:08:01,960
which stands for Massive Ordnance Air Blast.

109
00:08:02,520 --> 00:08:07,420
The mother of all bombs weighs approximately 21,600 pounds

110
00:08:07,420 --> 00:08:09,580
and is designed to detonate above the ground,

111
00:08:10,100 --> 00:08:12,560
creating a massive shockwave and blast radius.

112
00:08:13,420 --> 00:08:15,240
However, unlike the MOP,

113
00:08:15,480 --> 00:08:17,360
it does not have penetration capabilities.

114
00:08:17,360 --> 00:08:23,540
This MOP is capable of digging up to 200 feet underground

115
00:08:23,540 --> 00:08:24,480
before exploding,

116
00:08:25,600 --> 00:08:29,280
while the Massive Ordnance Penetrator can be deployed from bombers

117
00:08:29,280 --> 00:08:31,220
such as the B-2 Spirit aircraft.

118
00:08:32,480 --> 00:08:35,200
But this is not the case with the mother of all bombs

119
00:08:35,200 --> 00:08:39,180
is so large that it must be delivered via a C-130 aircraft

120
00:08:39,180 --> 00:08:40,280
using a pallet system.

121
00:08:41,080 --> 00:08:43,540
Once deployed, the bomb is dragged by a parachute

122
00:08:43,540 --> 00:08:45,000
and falls under gravity,

123
00:08:45,620 --> 00:08:47,620
guided by an inertial navigation system

124
00:08:47,620 --> 00:08:49,140
and military-grade GPS.

125
00:08:52,560 --> 00:08:55,500
On April 13, the U.S. dropped one of its largest

126
00:08:55,500 --> 00:08:59,140
non-nuclear bombs on a tunnel complex in eastern Afghanistan.

127
00:08:59,860 --> 00:09:00,760
When it detonated,

128
00:09:00,980 --> 00:09:03,540
the blast sucked all the oxygen out of the caves.
