i just found out that in FA credits he was the game designer and campaign creator.

Also CAG have you created a TV guided bomb or missile? I think it would be cool if that was possible. i mean with the laser/optical guidance you can switch targets but you cant really steer.


FOGM is the only steerable TV weapon I'm aware of.

Thanks for the info Kap...

Later versions of the AGM-62, the Walleye II, had extended range and were steerable, with target changing capability...

I had forgotten about the early weapons!
The early Walleye was steerable right from the beginning just in case the operator couldn't get a lock-on. I always liked Walleye because it actually WORKED at a time when a lot of missilery didn't and packed a heck of a punch when it hit home.
Add the Air Force HOBOs and AGM-130 to the list as well.

Early versions of the Walleye were not steerable, as they were fire and forget weapons after lockon. The Walleye II is the version that had the 2 way link for steering.

Nope. The Walleye was never a "fire and forget", the pod guided it all the way down via TV in the weapons nose. The operator could break into the automatic loop and guide it manually and even re-lock when necessary ( which was VERY necessary with low contrast targets ). The launch aircraft could turn away after launch but had to keep the radio link to the weapon. Walleye II was the 2000lb warhead version with the same guidance. Walleye ER/DL greatly modified the launch rules with a longer range and the ability to hand-off steering to other aircraft after launch as long as they had the ER/DL pod to do the guiding.

sorry kap but i have to disagree:

Quote:
Walleye was to provide the pilots of strike aircraft with a fire-and-forget high-precision air-to-ground weapon, i.e. the aircraft should be able to turn away as soon as the weapon was launched.
The Walleye was a glide bomb controlled by four large wings with trailing-edge control surfaces. In the nose it had a TV camera, which transmitted its image to a screen in the launching aircraft. When the pilot had acquired a target on this image, he "locked" the image and released the weapon. The guidance system then continually matched the current TV image with the locked one, and corrected the course of the missile to compensate any deviations.


further on, regarding manual steering of the weapon, a data link was required (for ERDL Ver)...similar to the AGM-130A-11 system.
Quote:
The next major step in the evolution of Walleye was the ERDL (Extended Range Data Link) modification. One drawback of the Walleye's guidance system was the requirement to lock the seeker onto the target before launch, meaning that the attack aircraft had to come relatively close to a potentially heavily defended target. The ERDL system equipped the Walleye with a two-way datalink, and the launch aircraft were equipped with an AN/AWW-9 (later AN/AWW-13) underwing data-link pod. The pilot could now launch the Walleye out of visual range of the target, turn away, watch the bomb's TV camera image, which was transmitted via the data-link, and lock-on to the target at any convenient moment. It was even possible to control the weapon from a different aircraft than that which launched the Walleye, and because of the limited number of data-link pods available, it was actually standard practice for one pod-equipped aircraft to guide Walleyes dropped by several attack aircraft (not simultaneously, though).


the early walleyes didn't require any steering after lock or launch.

Kap,

The 1st gen MK1 was indeed fire and forget, as it did TV matching, so it didnt require input from the pilot to guide it.

As expected, it didnt work well with 1960s technology and was eventually replaced with the controllable 2 way radio linked version...

The extended range version the MK3 ER (extended Range) was developed, and replaced it in production very early, with the same missile body and warhead and the same limited guidance.

From there the Walleye MK5 with the larger warhead and wings. From there the ERDL (data link added) version for guidance, changing target, or relocking onto target was developed. That would be the Walleye II with the datapod you speak of.

See data below...

It was even possible to control the weapon from a different aircraft than that which launched the Walleye, and because of the limited number of data-link pods available, it was actually standard practice for one pod-equipped aircraft to guide Walleyes dropped by several attack aircraft (not simultaneously, though). To use the beyond-visual-range capability to full effect, ERDL Walleyes were usually dropped from high altitude which led to glide ranges of up to 60000 m (65000 yd) for the Walleye II. The Walleye II ERDL also had slightly larger wings than the standard Walleye II. The initial production variants in 1975 were the MK 21 Walleye I ERDL and MK 23 Walleye II ERDL. These versions used a MK 46 guidance section and a MK 159 control section. The MK 22 was a Walleye I ERDL variant, which replaced these components with MK 53 and MK 165 guidance and control sections, respectively. I haven't found any reference to a Walleye MK 24, but it seems plausible that this nomenclature was reserved for a Walleye II ERDL variant with the MK 22's components. Production of the ERDL Walleyes ended in 1976, but in the late 1970s, around 1400 Walleye Is and 2400 Walleye IIs were converted to ERDL variants. The Walleye ERDL Trainer MK 27 was an inert training missile for both ERDL variants (MODs 3,4,5 were of Walleye II configuration) and was used for ground handling and captive-carry flight training.


I trained on several MKs of this weapon, so I am familiar with this guidance option. See all the data and all the versions of the walleye at the following URL:

Walleye II specifically and only refers to the 2,000lb version of the weapon, the 1,000lb version was the Walleye I.
Quote:
The small warhead of the original Walleye was useless against many hardened or large high value targets, like bridges and powerplants. Therefore the NWC developed a significantly enlarged version, initially known as "Fat Albert", but officially designated Guided Weapon MK 5 Walleye II (the small-warhead versions were renamed Walleye I). The Walleye II had a larger body with a 900 kg (2000 lb) MK 87 linear shaped-charge warhead, and much larger fins for further extended glide range.


The ER/DL versions were called "Walleye I ER/DL" for the 1,000lb version and "Walleye II ER/DL" for the 2,000lb version.

Sure Kap, whatever you say... :roll: :mrgreen:

(psssssssst... AGM-62A was Walleye I ER/DL, AGM-62B was Walleye II ER/DL, and all had sub MKs designating guidance and warhead and other changes...)

Thanks for supporting my point with that link!

Walleye II was the 2,000lb "larger warhead", show me a reference that dez's "Walleye II" with the 1,000lb warhead.

I have a source for the guidance question but it's a book and I'll have to transcribe it tonight.
Basically the Walleye was to improve on the Bullpup guidance system and make the guidance automatic rather than all manual as on Bullpup. The guidance systems were on the plane rather than the missile thus requiring a radio link. It wasn't "fire and forget" it only seemed that way. Much like a LASER guided bomb only with a radio link rather than the required LASER.

Then I guess I misunderstood what you were saying...

Only the Walleye 2 had the really larger and heavier warhead that reqired a missile re-design. Where did anyone say otherwise?

And...

The training missiles we had included some very old units and we were not able to relock targets after launch.

The missile that was the active weapon, yes as it had a 2 way radio link, the much older version initially used in Nam, no...

BTW below is what I posted about the Walleye in the weapons section of vnfawing.com back in 2004 when you asked me about the weapon...

CAG Hotshot wrote:
Yes and yes... But only the Walleye 1 early training missiles and the Walleye 2 ER/DL live weapon (much heavier and larger weapon with longer range and larger warhead), but I only dropped it, I didnt control it after drop as I never carried the data pod. The problem with the Walleye was the same with LGBs, namely weather and obscuring smoke(usually lit as a countermeasure by the enemy defending their target), but also the original Walleye had no real datalink and thus suffered accuracy issues if the missile lost lockon.

The Walleye 1 (improved) and Walleye 2 ER/DL required the second pilot with the guidance pod to stay in the area to 'fly' the bomb into target if it lost lock or there was a last minute target change. Any defensive action taken against the controlling aircraft would have consequences on the accuracy of the strike. The extended range of these later weapons improved the survival of the pilot with the guidance pod as it gave him a standoff capability...

It was a good weapon for the 1960s and 70s, but by the time I came along it was dated. There were more effective weapons in the arsenal...

LGBs were superior if you had a designator on your own aircraft, which would stay locked on the target automatically, or even better, a designator on the ground in the hands of friendly toops...

Mavericks also were superior with their full fire and forget capabilities...

CAG out...

Here's a few more steerable weapons:

Some of the Bullpups were steerable with a control stick, the missile's trajectory was watched through the gunsight.

IIRC the Kh-23 (AS-7) Kerry copied this guidance method.

The AJ.168 Martel was TV guided and steerable with a small control stick (for the terminal phase).

The Kh-59 and AGM-84 SLAM-ER Block 1F and later allow the pilot to select and reselect a target in the terminal phase. No manual joystick control that I know of.

Wasnt the orignal AT-3 Sagger missile flown like the Bullpup?

About the AT-3 Sagger, Wikipedia says:

Quote:
The missile is guided to the target by means of a small joystick (9S415), which requires profound training of the operator.
:lol:

Also, the first air to air missile (albeit never used in combat), the WWII German Ruhrstahl X-4 was joystick controlled with trailing wires.
