What is an empty quiver?

Empty Quiver refers to the seizure, theft, or loss of a functioning nuclear weapon.

Is Broken Arrow a real military term?

The U.S. military uses the term “Broken Arrow” to refer to an accident that involves nuclear weapons or nuclear weapons components, but does not create the risk of nuclear war. A Broken Arrow is different from a “Nucflash,” which refers to a possible nuclear detonation or other serious incident that may lead to war.

What is a Bent Spear?

A bent spear, in Pentagon parlance, identifies a “significant incident” involving a nuclear weapon, warhead, or component, or a vehicle loaded with nuclear materials. ... It comprises unauthorized launch, nuclear detonation, or jettisoning of a nuclear weapon.

What is the code name for a lost nuclear weapon?

"Broken Arrow" is the name given to nuclear weapon accidents, whether they be by accidental launching, firing, detonating, theft or loss of the weapon. The U.S. admits to having 32 broken arrows worldwide, with six nuclear weapons having been lost and never recovered.

Did the US nuke the moon?

The project was never carried out, being cancelled after "Air Force officials decided its risks outweighed its benefits", and because a Moon landing would undoubtedly be a more popular achievement in the eyes of the American and international public alike.

What happens if a nuke goes off in the ocean?

Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. ... During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous below 2,000 feet (610 m).

Can a nuke cause a tsunami?

The tests revealed that a single explosion would not produce a tsunami, but concluded that a line of 2,000,000 kg (4,400,000 lb) of explosives about 8 km (5.

Is a grenade more dangerous underwater?

Underwater explosion is no more different in concept of detonation than the explosion in the air, but the effects of this kind of explosion are. It is well known that underwater explosion cause more damage than the same amount of explosive detonated in the air [1].

Will a grenade explode underwater?

However, an underwater explosion transmits pressure with greater intensity over a longer distance. If you stood outside of shrapnel range for an exploding hand grenade, you'd likely remain unharmed. If you stood at the same range to an underwater explosion, the pressure wave would probably kill you [source: Landsberg].

Can you survive a grenade?

Despite these rare instances, however, the odds of survival are extremely slim. With modern medicine, however, odds are greatly increased when compared to falling on a grenade in the 20th century.

How can shock wave kill you?

Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums. Shock waves produced by explosive events have two distinct components, the positive and negative wave.

How dangerous is a shockwave?

A shock wave can be destructive because it vibrates the material around the point in an extremely hard and fast wave, which causes other things that the material touches to vibrate too, and even make them explode. Shock waves make bombs more dangerous and sometimes are the most dangerous part of an explosion.

What is blast effect?

Blast waves occur when the compression of air in front of the pressure wave heats and accelerates air molecules, leading to a sudden increase in overpressure and temperature, which are transmitted into the surrounding environment as a propagating shock wave known as the blast wave (Figure 7-1).

What PSI is deadly?

Overpressure
Overpressure Physical Effects
10 psi Reinforced concrete buildings are severely damaged or demolished. Most people are killed.
5 psi Most buildings collapse. Injuries are universal, fatalities are widespread.
3 psi Residential structures collapse. Serious injuries are common, fatalities may occur.

How much damage can 1 kg of TNT do?

Under controlled conditions one kilogram of TNT can destroy (or even obliterate) a small vehicle. The approximate radiant heat energy released during 3-phase, 600 V, 100 kA arcing fault in a 0.

Can gasoline explode without a spark?

That's a lot of explosive energy stored in a typical, full gas tank! ... You could heat the gasoline up to a high enough temperature that it could ignite spontaneously: without even a spark.

What does a shockwave do to your body?

The blast wave energy moves through the torso to the brain. This can potentially cause damage to tiny cerebral blood vessels, stretching and damaging neural cells in the brain.

Can shockwaves cause damage?

The passage of a strong shock wave through the human body, for example, causes severe damage owing to the large instantaneous pressure change.

What does Shockwave feel like?

Shockwave therapy is a non-invasive, non-surgical treatment, but you might feel a little pain or discomfort in the treatment area during the procedure. Most patients say it feels like small pulses against the skin. Your specialist may be able to adjust the way they use the shockwave device if your pain is significant.

What causes a shockwave?

Shock waves are formed when a pressure front moves at supersonic speeds and pushes on the surrounding air. ... Over longer distances, a shock wave can change from a nonlinear wave into a linear wave, degenerating into a conventional sound wave as it heats the air and loses energy.

What's the difference between Shockwave and Soundwave?

Shock waves differ from sound waves in that the wave front, in which compression takes place, is a region of sudden and violent change in stress, density, and temperature. Because of this, shock waves propagate in a manner different from that of ordinary acoustic waves.

How often can you do shock wave therapy?

Shockwave treatment is usually done once a week for 3-6 weeks, depending on results. The treatment itself can cause mild discomfort, but it only last 4-5 minutes, and the intensity can be adjusted to keep it comfortable.

What is a normal shock wave?

Shock waves are very small regions in the gas where the gas properties change by a large amount. Across a shock wave, the static pressure, temperature, and gas density increases almost instantaneously. ... If the shock wave is perpendicular to the flow direction it is called a normal shock.

Is stagnation pressure constant in isentropic flow?

Fluid Machinery. If we know the local temperature (T) and Mach number (Ma), we can fine out the stagnation temperature . Consequently, isentropic relations can be used to obtain stagnation pressure and stagnation density as. ... It is understood that all stagnation properties are constant along an isentropic flow.

Is stagnation temperature constant across a normal shock?

The ratio of stagnation temperatures remains constant across a normal shock since the process is adiabatic.

What is Shockwave used for?

Extracorporeal shock wave therapy (ESWT) is a noninvasive treatment that involves delivery of shock waves to injured soft tissue to reduce pain and promote healing.

Is Shockwave Therapy illegal?

A treatment called extracorporeal shockwave therapy (ESWT) is used in patients both human and equine to speed healing of injured tendons and ligaments. ... For that reason, horse racing authorities have banned the use of ESWT for horses within 10 days of a race or sporting event.

How much does it cost for shockwave therapy?

High-energy shockwave does have higher costs associated with it in comparison to low-energy ESWT and can range from $1,000 to $3,000 total. However, treatment with high-energy ESWT does have the advantage of one-time treatment.

Is Shockwave the same as Flash?

"Adobe Flash Player" and "Shockwave Flash" does indeed refer to the same thing. It is the Shockwave for director or Shockwave player that is different. "Adobe Flash Player" and "Shockwave Flash" does indeed refer to the same thing.
