The Northrop F-89 Scorpion was an early American jet-powered fighter designed from the outset as an all-weather interceptor, the first jet-powered aircraft designed as such. Though its straight wings limited its performance, it was among the first United States Air Force (USAF) jet fighters with guided missiles, and notably the first combat aircraft armed with air-to-air nuclear weapons (the unguided Genie rocket).
The Scorpion stemmed from a United States Army Air Forces (USAAF) Air Technical Service Command specification ("Military Characteristics for All-Weather Fighting Aircraft") for a night fighter to replace the P-61 Black Widow. The preliminary specification, sent to aircraft manufacturers on 28 August 1945, required two engines and an armament of six guns, either .60-caliber (15 mm) machine guns or 20-millimeter (0.79 in) autocannon. The revised specification was issued on 23 November; it did not specify jet propulsion, but the desired maximum speed of 530 miles per hour (850 km/h) virtually dictated that all the submissions would be jet powered. The aircraft was to be armed with aerial rockets stored internally and six guns split between two flexible mounts, four guns forward and two in the rear. Each mount had to be capable of 15° of movement from the longitudinal axis of the aircraft. Each mount's guns were to be automatically controlled by radar. For ground attack, it had to be capable of carrying 1,000-pound (450 kg) bombs and to be able to carry a minimum of eight rockets externally.Bell Aircraft, Consolidated-Vultee, Douglas Aircraft, Goodyear, Northrop and Curtiss-Wright all submitted proposals. In March 1946, the USAAF selected the Curtiss-Wright XP-87, adapted from their proposed XA-43 attack aircraft, and Northrop's N-24 design, one of four submitted by the company.
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognised by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm (Typhlochactas mitchelli) to 23 cm (Heterometrus swammerdami).
The evolutionary history of scorpions goes back to the Silurian era 430 million years ago. They have adapted to a wide range of environmental conditions and can now be found on all continents except Antarctica. Scorpions number about 1750 described species, with 13 extant families recognised to date. Only about 25 of these species are known to have venom capable of killing a human being.The taxonomy has undergone changes and is likely to change further, as genetic studies are bringing forth new information.
Scorpion stings are painful but are usually harmless. For stings from species found in the United States, no treatment is normally needed for healthy adults although medical care should be sought for children and for the elderly. Stings from species found elsewhere may require medical attention.
Made by Northrop Aircraft for the U.S. Air Force Air Defense Command, this promotional film MRS. JONES, MEET YOUR PARTNERS features General Nathan F. Twining speaking about the group's mission: to protect the USA from enemy attack, especially nuclear attack. It also showcases the F-89 Scorpion interceptor. The film is a bit fragmentary but apparently featured a civilian housewife "Mrs. Jones", who has volunteered as a aircraft spotter with the Ground Observer Corps, touring the advanced USAF ADC infrastructure. At 55 seconds, the film shows the Air Defense Direction Center, the heart of the nation's air defense system. Here, the nation's skies are constantly scanned and then F-89D aircraft dispatched to intercept any hostile incoming aircraft. At 2:00, a large table is shown where markers ...
The Northrop F-89 Scorpion was an early American jet-powered all-weather interceptor. It has the distinction of being the first combat aircraft armed with nuclear weapons, (the Genie rocket) for air-to-air use.

Taken in 2012 during the reassembly process of the museum's latest outdoor display acquisition, these images show the Scorpion Squad at work. This Cold War aircraft is the Northrop F-89J fighter which will be displayed as an F-89C fighter with period USAF markings. This F-89 Scorpion was shipped to Selfridge Air National Guard Base in April of 2012 and offloaded to the work site where the first phase of the reassembly process began. Ten seasoned, hand-picked volunteers of the Selfridge Military Air Museum were assigned to the project, which is now approximately 90% complete. It can be seen in its designated placement at the museum's outdoor air park. The Scorpion ...
The Northrop F-89 Scorpion designed by Jack Northrop and manufactured by Northrop Corporation is an American jet-powered fighter interceptor aircraft. The F-89 Scorpion said to be the most capable of the first-generation all weather jet interceptor aircraft. The Northrop F-89 was created in response to a USAF proposal for a successor to the P-61 Black Widow. The maiden flight of the F-89 Scorpion was on the 16th of August 1948 and it went into service on September 1950. Primary users were the United States Air Force and the Air National Guard. There were approx. 1,050 and 2 prototypes F-89 Scorpion produced. The F-89 Scorpion retired from service in 1969.

Underneath a big clock
At the corner of 5th Avenue and 22nd Street
I stood and waited for a girl I knew
At the spot where we agreed to meet
It was four minutes of two
At four of two, I stood waiting for the girl
I was four minutes early for the date we had planned
I was planning to say I was in love with her
Just as soon as she showed for a two o'clock date
And the clock said four of two
At four of two, I was staring into space
She was not yet late, according to the clock
I was feeling nervous so I kept looking up
At the clock sticking out of the side of the building
And it still said four of two
At four of two, I began to feel tired
And I rubbed my eyes, and again I checked the time
It seemed as if the sky was growing dark
But I felt reassured when I looked at the clock
And it still said four of two
I lay my head down on the sidewalk
So in case she were coming I would have a better view
But no one was there so I stretched out
And closed my eyes for a second or two
It was four minutes of two
At once I awoke to a futuristic world
There were flying cars and gigantic metal bugs
I'd grown a beard, it was long and white
But I knew that the girl would be coming very soon
For though everything had changed, there was still that clock
