One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

initiator explosives, those most sensitive to heat, shock, electric spark, friction, and impact. They are usually high explosives such as the fulminates and lead azide, although lead azide may be sensitized with a small amount of lead styphnate.

Cap-sensitive explosives: The explosive can be fully detonated with a measurable unconfined velocity in low diameters (1 inch) by initiating with a single detonator of No. Booster-sensitive explosives (blasting agent): This type of explosive is detonated only when a booster of sufficient power is used to initiate it.

Commonly used military energetic compounds include the explosives 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) [1].

Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications….Composition.

Composition C4 is a plastic explosive used in military operations.

The Semtex mixtures each contain differing proportions of PETN, RDX, a styrene–butadiene binder, a Sudan dye, plasticizers and in Semtex 1A an antioxidant. C4 mixtures contain RDX, polyisobutylene, motor oil and plasticizers.

C-4 is a plastic explosive substance similar in structure to Semtex that is used by both military and terrorist organizations. It has a reputation for producing a buzz as well as a bang.

C4 is more powerful than TNT and is quite stable. Supposedly, a bullet can be shot into a stick of C4 without causing it to detonate. To explode a stick of C4 requires a detonator.

Azidoazide azide

A block of C4 plastic explosives can withstand a rifle shot without exploding. You can even set one on fire without too much worry.

GBU-43 Massive Ordnance Air Blast

China has developed a massive bomb, said to be the country’s answer to the US-built ‘Mother of All Bombs’, the most powerful non-nuclear weapon, official media reported on Friday.

Number of nuclear warheads worldwide as of January 2020

The United States has a two-man rule in place at nuclear launch facilities, and while only the president can order the release of nuclear weapons, the order must be verified by the secretary of defense to be an authentic order given by the president (there is a hierarchy of succession in the event that the president is …

One major component is Ground-Based Midcourse Defense (GMD), consisting of ground-based interceptor (GBI) missiles and radar in the United States in Alaska, which would intercept incoming warheads in space. Currently some GBI missiles are located at Vandenberg AFB in California.

Under the theory of deterrence, America’s nuclear arsenal—currently made up of 3,800 warheads—sends a message to other nuclear-armed countries. Many consider American deterrence a success, pointing to the fact that no country has ever attacked the United States with nuclear weapons.

The President does not enlist in, and he is not inducted or drafted into, the armed forces. The last two War Presidents, President Wilson and President Roosevelt, both clearly recognized the civilian nature of the President’s position as Commander in Chief.

The Insurrection Act of 1807 is a United States federal law that empowers the President of the United States to deploy U.S. military and federalized National Guard troops within the United States in particular circumstances, such as to suppress civil disorder, insurrection, or rebellion.

There are around 19 million U.S. veterans as of this year, according to data from the Department of Veterans Affairs, representing less than 10% of the total U.S. adult population.

The total number of active duty military personnel in 2018 amounted to 1.3 million people….

61 million adults in the United States live with a disability. 26 percent (one in 4) of adults in the United States have some type of disability.

331,002,651 people

The estimated population of the U.S. was approximately 328.2 million in 2019, and the largest age group was adults aged 25 to 29. There were twelve million males in this age category and around 11.5 million females.

As of July 2016, White Americans are the racial majority. Hispanic and Latino Americans are the largest ethnic minority, comprising an estimated 18% of the population. African Americans are the second largest racial minority, comprising an estimated 13.4% of the population.

The 75 to 84 age group share of the older population was around 14.3 million or 29 percent— more than double the number and proportion (6.3 million or 13 percent) for those 85 and older (Table 1).

Because of increases in life expectancy at older ages, people 90 and older now comprise 4.7 percent of the older population (age 65 and older), as compared with only 2.8 percent in 1980. By 2050, this share is likely to reach 10 percent.

A person is considered even older at about age 75. Many people are still active at this age, but they may notice that their hearing is not as good or they are not seeing as well as they did before. People who are over 85 are considered the “oldest” of the old.
