Hey guys! I'm a long time viewer of these forums. Now I have myself a question. I plan to build a HUMVEE with Pro Art Models Hardtop, Interior Set, ASK and Blast Models Wheels. So far so good. But can I attach a GPK to the HUMVEEs top? I only saw pics of HUMVEEs w/hardtop carrying M2s w/o any gunners shield or turret... Thnx in advance!

The hard-top is just fibreglass so unlikely it would support the weight of the GPK, but I could be wrong.

Frenchy will probably manage to produce a pic of this combination...

Okay, I've also read about the hardtop consisting of fibreglass. But let's see if someone produces another opinion...

hi same opinion as Sean.
And I never see this. The roof with GPK are metal up-armoured roof

Number of Humvee photos on my HD: 15000
Number of Hardtop w/GPK photos on my HD: 0

And I've got the same opinion as Sean - GPK is too heavy for Helmet Hardtop roof.

Hey juankar, many thanks! You do have a really impressive collection of humvee pix (so many cool variants, so little funds to buy kits and aftermarket sets...).

In your first album I found a humvee with a hardtop and some self-made additional armor including some turret-style arranged plates on the top (photo nr. 70). There are a few hardtop humvees, but none sporting a GPK...

Nice lookin' humvee, juankar. I'm also planning to do a Legends M1114 or M1151 in the future (if enough cash is available...).

But I still hope to find a possibility to use my GPK on that hardtop HUMVEE

The Helmet Hardtop version of the HMMWV is made of fiberglass, but does have internal steel support tubes that will support a weapons mount. I am not familiar w/the GPK MG(?), but I bet it can support it if it can support an M2 .50 cal or a Mk 19 automatic grenade launcher.

@ Juankar: thank you for the heads-up

@ Gino: That's exactly what I thought myself. If the hardtop can handle the weapons ring, shouldn't it also be able to bear the GPK? Perhaps there will be more gents to bring in some skilled input...

DOH!! Now I am following. GPK = Gunner's Protection Kit, a.k.a. the MG shield and armored surround around the gunner.

The reason you don't see GPKs on the Helmet Hardtop version is that it is an unarmored HMMWV. There would be no purpose to place an armored cupola on top of an unarmored, soft-skinned vehicle. The GPKs are only used on M1114 and later uparmored HMMWVs and other armored vehicles.

Gino, yes, you are right as it doesn't have much sense, altough I will also have the ASK kit on my hardtop humvee (I've already found pix of these type of "up-armored" hardtop humvees).

So the question is really more like "is it technically feasable?"

Gino, I think that the term GPK design the complete armoured turret :
Citation :
Objective Gunner Protection Kit (O-GPK): O-GPK is a turret mounted on armed vehicles and provides gunners all-over protection from things such as bomb fragments and small arms fire. Soldiers can rotate the turret and gun using a joystick (and our parents told us playing videogames was a waste of time), which reduces distraction.

So it's more heavy than the gun itself

PS sorry, I dont read the later post before writing :-(

Thank you for your comment, Pascal! And Juankar, thanks for the links. Still searching infos about GPK/hardtop.

Just to clarify quickly, the GPK and the OGPK are not the same. The OGPK should weight considerably more with its higher sides and armored glass windows.

You're right, the O-GPK looks much heavier than the GPK.

As stated, this photo is not of a GPK though. It looks to be of the "Hillbilly" armor, which looks like plates of steel added to the original ring mount to provide some protection to the gunner. This makes sense since it also has ASK which was first generation add-on armor used early in the conflict to provide protection to soft-skinned HMMWVs before armored ones could be fielded.

I still don't believe any actual GPKs were added to the soft-skinned "Helmet Hardtop" HMMWVs. The GPK is a feature of uparmored HMMWVs.

Not this time Sean...Juan has beaten me to it (with a picture I also have in one of my Picasa albums )

But the fiberglass roof is OK for an A/C unit


@Juan : I'm glad to see it seems you've been pleased with my 3 Picasa Humvee albums....

@ Gino: Yes I also noticed this being some self-made armor for the gunner. Meanwhile I also think there weren't any hardtop Humvees driving around with a GPK.

@ Frenchy: Thnx for the pic! I've also seen some hardtops with AIRCO mounted. I got one of these in Pro Art Models HArD kit. Perhaps I will mount this on top. Eventually this will become something like a "what-if" build, 'cause I don't know any other possibility to use my single GPK.

Suggestions?
