Started this page when researching the Sidewinder missile (Wiki) developed by China Lake Naval Weapons Center (Wiki), aka: Naval Ordnance Test Center (NOTS).  This missile uses IR guidance.  See the Related paragraph below for more IR and optical devices.
It turns out that the Navy was behind the VT Fuze (Wiki) and that they both depend on a radio fuze that functions in a very similar manner.  That's to say a three dimensional map of the trigger envelope comes close to a three dimensional map of the shrapnel.

The first patent on what turned out to be RADAR (Wiki) is this one:
1981884 System for detecting objects by radio, Lawrence A Hyland (Wiki), Albert H. Taylor (Wiki), Leo C. Young (Wiki), Nov 27, 1934, 342/27, 367/128, 342/453, 340/991, 342/407 -

and three other antennas.

                      Labratory, Anacostia, D.C. late 1930s (from Wiki)
Note that this first RADAR was not pulsed, but rather a CW (Wiki) type more like a Doppler RADAR (Wiki).  The SD RADAR ( used on subs early in W.W.II only had an "A" range (2 to 30 miles) display, not the PPI (Wiki) rotating type display.  In 1943 the SJ RADAR with PPI display was introduced.

Sep 2017 - a photo dated September, 5, 1947 on eBay has the following caption:
"General Electric's motion detector, using the principle of the VT fuze, is displayed here by W.C. White, left, Research Laboratory electrinics engineer, and H.S. Lasher, a research engineer.  Five-inch-long microwaves are sent out by the papabolic (sic) reflector, which also receives the reflected signal.  When motion is detected the device can be made to operate a light, ring a bell, and perform other tasks."

A 5 inch wavelength corresponds to a frequency of (speed of light / 5") 2,362 Mhz (Wiki: S Band)

In "
The Deadly Fuze" (Ref 1) it's mentioned that British worked on a Photo Electric Fuze (as did the U.S.) so I searched for patents related to that and there are a lot of them.  Some of them where the publication date is about 20 years after the filing date indicating that they were classified secret.  The level of detail indicates that they may be been manufactured in production quantities, probably for  some special application.  Note that the Sidewinder missile uses thermal IR for guidance and so a PE Fuze that was sensitive to thermal IR would work very well and not be susceptible to jamming.

Note that proximity fuzes can be used on different platforms.  Bombs and rockets experience much less acceleration than artillery shells.  Also bombs and rockets do not spin at all.  So the early work on proximity fuzes was done on bombs and rockets and then later, as high-G components were developed, they applied to shells.

While there are patents the have illustrations that look like production VT fuses, I think 2959128 and more important 3001476 are the heart of the magnetic proximity fuse based on the time delay between the priority date and issue date, i.e. top secret classification.  These patents are about antennas that can stand the very high wind velocity of projectiles and not vibrate.  The method of operation is to have a magnet (either electro or permanent) and a coil to sense a change in the magnetic filed.  This is very different from the "magnetic influence" exploder used on W.W.II torpedoes which did NOT work.

Flak Training for Pilots in WW 2 - T.F. I-3389, 1944 - no mention of lethal radius, i.e. how far the burst needs to be for safety.
Horizontal: 300 MPH = 440 feet per second,
Vertical: roughly 1000 feet per second, if 50 foot lethal radius then timing accuracy of 50 milli seconds needed.  There are two aspects how repeatable are the shells and are they set to the correct time delay.  The proximity fuze was developed to solve this problem where NBS and Harry Diamond were involved.


Proximity Fuzes

There are two fundamentally different weapons platforms that make use of the proximity fuze and the key difference is if it spins on the long axis.

Rifled Barrel

Projectiles fried from a rifled barrel have very high (20,000G) set back forces and spin.  Both of these make a reserve battery that uses a glass vial of battery acid work well.  The set back force can be use with a "breaker" to open the glass capsule.  The spin can be used to force the acid into the battery plates.

Development of these fuzes was done by the Navy along with the Johns Hopkins Applied Physics Laboratory.

Smooth Bore (see Army Fuzes below)

Mortars, rockets with non rolling air frames and bombs have lower forces and no spin so reserve batteries are not a good choice.

The development of these fuzes was done by the Army and Harry Diamond leading a group at the NBS which included Wilbur S. Hinman, Jr., Allen V. Astin, Cledo Brunetti, Jacob Rabinow. Also see Radiosonde: Theory & James A. Van Allen (Wiki)

Bomb fuzes need to work in very cold temperatures where dry batteries have low or no output.

It turns out this is in fact for a 5" rocket rather than a rifled gun, so I need to move it to a different paragraph.

This fuze appears in Ref 9: OP 1480 VT Fuzes for Projectiles and Spin-Stabalized Rockets, 15 May 1946.

Reserve Batteries

A reserve battery (Wiki) "is a primary battery where part is isolated until the battery needs to be used. When long storage is required, reserve batteries are often used, since the active chemicals of the cell are segregated until needed, thus reducing self-discharge.".  They are used in Sonobuoys where salt water is the electrolyte and Radiosondes where room temperature tap water is used for activation as well as proximity fuzes.

This is one of the modular components of the proximity fuse.  It's my understanding that all of the proximity fuzes use the same reserve battery, setback switch, Centrifugal switch and I suspect other components so that they do not need to be engineered for every new project.

See Ref 45 for a good explanation of how the reserve battery for artillery shells works.

Glass ampule

Capsule to hold reserve battery electrolyte.  This is a promotional item made by GE.  There were other promotional ads, like for the vacuum tubes that would survive being fired from a gun.
If 30 million were made over 2 years that's about 40,000 per day.
Somewhere else I read that Christmas tree lights were impossible to get (the box says "hard to get").

Fuzes designed for artillery make use of the very high G forces to break the glass capsule allowing the reserve battery to operate.  It's not clear to me what activates the reserve battery in a bomb or missile proximity fuze.  Reference 11 (pg 134) says that rockets have enough set back force to break the glass. 

Bombs use a generator rather than reserve battery as do some rockets.  Generators used either a propeller or turbine.  In some cases the generator shaft turned a gear train that set off the initiator after some number of revolutions as a self destruct mechanism.  The frequencies coming out of the generator, no matter what the bomb or missile speed, needed to be out of the audio range of the received signal.  Hence the 6-pole generator rather than a 3-pole design which would have cost less.

The generators were AC alternators with stationary windings for filament and plate voltages and rotors holding permanent magnets (then Alnico II or IV).  That's to say they were essentially DC permanent magnet motors but without brushes.  Ref 11 pg 145.

Torpedoes used an internal impeller powered generator for electrical power.  See the Mk 6-5 Exploder of 1945.  This also acts as a Safe and Arm since the exploder can not work until the HV capacitor is charged.

                    mighty secret weapon of World War II
There's an ad by the National Carbon Company (Eveready) "The Shell with a Radio Brain! . . . the true story of a mighty secret weapon of World War II", that claims Eveready batteries were used in the VT Fuse.  I don't see how that's possible other than in prototypes.  If you know more about this let me know.
The problem with primary batteries is their limited shelf life.  Reserve batteries are a way to get around that problem.

One of the biggest problems making the glass
capsule was to make sure that it broke only when
you wanted it to.  It had to be strong enough not
to break when handling ammunition; yet it had
to break when fired in low velocity projectiles
(rockets) or high velocity projectiles (anti-air
craft).  G-E's glass technologists solved the problem
and produced the capsules on machines used to
make Christmas tree lamp bulbs - which is one
reason why Christmas tree lights were hard to get!

The bulbs are about 5/8" diameter x 1.4" long.
Over thirty million of these glass capsules
were produced by General Electric's Lamp
Department to make the "VT" radio prox-
imity fuse a practical success and one of
our most effective defenses against Kamikaze
attacks (Jap suicide planes).  When the
shell is fired the capsule shatters, freeing
the electrolyte which makes the battery
operative.  A tiny "radio station" then
sends out radio waves which, if reflected
by any target 70 feet or less away, detonate
the projectile at the ideal distance for
maximum effect.

This unit depends on the absorbent material at the bottom all the cells to suck up all the electrolyte.  If this does not happen then the series connected cells will short out.  I very much doubt this was a viable product, but it has the look and feel of the reserve battery used in the proximity fuze.

Wales also has patents on the Bazooka base detonator

The Hot Gas - Generator system is covered in patents 2695365 & 3001474 - These hot gas systems can only provide power for tens of seconds, long enough for an air-to-air missile flight, but not long enough for some air-to-ground applications.

The hot gas comes from a rocket fuel grain.

May have been used in Proximity Fuzes from a thread on the Antique Radios web site:
Since Proximity Fuze tubes would have been custom designed since they were made in very high volumes, the filament voltage would have been 1.25, i.e. to work with a single cell battery.  6.3 V filaments might be for fuzes with wind powered generators, like on bombs, rockets and mortars.

From a post on the Tube Collectors Association:
The submin types that Raytheon theoretically registered in 1948 were the 2B24, 2C27, and 2E27. The "registration" was type-number-only because the characteristics were considered classified (BFD).  The unclassified ones were the 2D29 and 2E29.

Sputnik, Transit & GPS

I watched a documentary on Amazon Prime (17 Feb 2019) titled "The Lonely Halls Meeting" (IMDB).  It gave the credit to the Air Force for inventing GPS, but after finding the patent shown in the documentary (the patent number was hidden, but the filing date May 12, 1958 was shown I found the patent and it was for the Transit (Wiki) navigation system, not GPS. So I initially posted the following on my Radar Warning Receiver web page.  But after doing more research I'm moving it here because it looks to me like the Navy was really the father of GPS (even though China Lake was not involved as far as I know).

A major event was the launch of Sputnik (Wiki) On 4 October 1957.

After the Powers U-2 shoot down on Mayday (1 May) 1960 these overflights were cancelled.  They were replaced by the Corona (Wiki) photo reconnaissance and GRAB (Wiki) satellites, both of which were operational within a year.  Note the GRAB ELINT (Wiki) package was designed to detect S-band radar, as used by the SA-2 (Wiki) that shot down Power's U-2 (Wiki).  This allowed mapping the location and functional parameters of all the SA-2 systems from space.

There is a GRAB display at the National Cryptographic Museum because it was the first ELINT (Wiki) satellite also see Spy Satellite (Wiki).

                      Transit Satellites
Note the photo at the top of the Wiki page for the Transit satellite shows the GRAB satellite sitting on top of it for a dual satellite launch.

Time & Frequency

3172108 Method of navigation, Frank T Mcclure, 1965-03-02, -  Transit error 0.03 to 0.07 miles (158 to 369 feet).  Because of the Earth's rotation there is no ambiguity for a receiver to the East or West of the satellite ground path. Clock needs to be good to 1 part in 107.  This is well within the capability of the first generation HP 5060A Cesium standard that came out in 1964.  The patent says crystal oscillators will work, so maybe URQ-10 or URQ-23 were used with Transit? Let me know.

"The precision time standard 51 provides highly accurate timing signals in order that one mile accuracy may be obtained. The time standard 51 may include a crystal oscillator, similar to the oscillator 31 illustrated in FIG. 4, together with a time comparator 52 providing a correcting means which is responsive to the satellite timing signals. Alternatively, time standard 51 may comprise an atomic clock in which case the need for satellite timing signals is eliminated."
75 & 150 MHz operation.  

Another response to Sputnik was the development of the Transit (Wiki) navigation satellite system (Electronics:Sputnik & Transit & GPS).  Transit depends on having an atomic frequency standard as part of the receiver, which makes for a very expensive receiving system.  Also the Nautilus (Wiki) Submarine needed to be on the surface for a long time (maybe a half hour or more) in order to record the full Doppler (Wiki) curve.  So a more cost effective satellite navigation system was wanted where the receivers cost less and the Time To First Fix (TTFF) was much shorter.  That system turned out to be GPS (Wiki - history).

There is an Amazon Prime documentary titled "The Lonely Halls Meeting" (IMDB) with some information on the development of GPS from the Air Force perspective.  The following patent was referenced as the invention of GPS, but it relates to the Transit (Wiki) satellite navigation system.  They point to Bradford Parkinson (Wiki) as the "inventor" of GPS but Wiki says "he led the re-architecture of the concept".  His first patent (5726659) was filed in 1995.  The GPS Wiki says "Roger L. Easton of the Naval Research LaboratoryIvan A. Getting (Wiki: Project Nobska) of The Aerospace Corporation, and Bradford Parkinson of the Applied Physics Laboratory are credited with inventing it."  So the documentary is slanted in favor of the Air Force.  Note that the principal inventor and designer of the Global Positioning System, Roger Easton is not mentioned in the documentary.  He holds a number of patents starting in 1955.  The documentary also claimed that CDMA (Wiki) was developed for GPS, but the Wiki page says it came from Russia.  While GPS does make use of CDMA, I'm not aware of it being invented on the GPS program.  Gold code (Wiki) is an implementation of CDMA that minimizes the cross correlation between signals and was developed within GPS.  Maybe that's what they meant to say in the documentary?
The Space Review: Who invented the Global Positioning System? by Richard Easton (Roger's son), May 22, 2006 - Has a table comparing the Navy's Timation sattelite (Wiki)) and the Air Force 621B satellite (Wiki).  To my reading Timation was the key contributor.

Analysis of the "range and Range Rate" Tracking System, 1962 - sidetone ranging on page 3
the book "High Precision Navigation and Geodetic Methods by Linkwitz & Hangleiter, 1989, - page 475 has equations and details and that STR is much better than Time Of Flight (Wiki: TOA)

Note 2: Pseudo Random Sequence

Because of the process gain (Wiki) involved with the pseudo random code the GPS signal on the surface of the Earth is below the thermal noise (Wiki).  This means that someone who looks for the signal on a spectrum analyzer will not see it.  That's to say it is a covert signal.  In order to detect the GPS signal you need to know how it's modulated.

Another aspect of this is that all GPS satellites transmit on the same channel.  That's to say they all are interfering with each other.  So the signal to noise ratio is always the same since the interfering signals are always about the same.  Improving the s/n ratio can only be done by good processing of the signal, not conventional analog methods.

Note 3 Orbits

The documentary says the orbit height was chosen based on the throw weight (Wiki) of the known type of booster rocket and the trade off between the satellite weight versus the weight of the inter orbit rocket.  The result was an orbit with a period (Wiki) around 12 hours.  I've also read that a period of 12:00:00 sidereal (Wiki) hours was chosen so that the ground track (Wiki) would repeat.  This would make testing the system much easier during the time before all the satellites were functional.

Missile Gap

Around this time the Air Force and the Gaither Committee (1957) were saying there was a missile gap (Wiki), i.e. that Russia had many more ballistic missiles than the US, so there should be a major spending program to build more missiles.  A strong motivator for the U-2 program and spy satellites was to get an answer to this question.  It turns out there was no "missile gap". see Aerial Photography Ref 7

Patent Dates

Projects at China lake (it's not easy to correlate the patents with their project).  The below table is in more or less chronological order based on patent issue date.

Most patents are granted within a range of the same year to a few years after the application.  If the subject is a SECRET then the publication is delayed, in some cases forever, or other cases up to 40 years.  So whenever there's a long time delay between application (or priority) date and Issue/Publication date something special may be going on.

PS It's highly probable that most patents are granted on Tuesday.  I've never seen a non Tuesday publication date.  Be suspicious of a patent date that is not Tuesday.

Photoelectric Fuzes

PE fuzes were used on the 4.5" solid fuel M-8 rocket (Wiki). see Ref 7 for a lot of information on PE fuzes and some info on radio proximity fuzes.  The rocket was launched from the ground and Army Air Force planes.  2.5 million rockets were made for W.W.II.  The ground launched rocket was inaccurate.  The air launched rocket was inferior to the Navy 5" High Velocity Aircraft Rocket (Wiki: HVAR). 

The warhead for the HVAR included shells for the Navy 5"/38 gun.  Note these shells were fitted with radio proximity fuzes when used on guns so probably could also be used on the HVAR.

The TDU-11/B Rocket was used as a target for the Sidewinder missile. It was fitted with four 1" dia x 10" long flares.  The TDU-11 could be fired from the same plane that would launch the AIM-9 Sidewinder.


The tubes used in the proximity fuzes would work up to 200 Mhz.  The T-5 fuze for the M-8 rocket (Wiki) used three frequencies below that upper limit with code names of Red, Yellow, Green which were near the resonant frequency of the M8 rocket (Wiki).  It was 33" (0.838m) long.  If the resonant frequency corresponds to 1/2 wavelength then a wavelength is 1.676 m or a frequency of 179 MHz.  Ref 11 (pg 159).  Note Ref 11 was published in 1947 with a SECRET classification but the frequencies were at a higher classification, at least TOP SECRET.  Yet it's fairly easy to figure out.

For bombs the frequency codes were White and Brown.  Later a single frequency "Brown-20" was used for all bombs between 100 and 2,000 pounds.
