iblawi:They would be back making the same unfounded claims in a couple months time. |
jl115:And then there is the fact that the Rooivalk is very heavily dependent on French technology. You're lying to yourself. kabe1: |
jl115:You're telling yourself lies. Shocking thing is you believe those lies. |
But – and this is a very important point – South Africa could not design and build a complete helicopter from scratch. The design, development and manufacture of the necessary powerplant and dynamics system (rotor head, main and tail rotors, and main and tail gearboxes) were beyond this country’s capabilities. Acquiring such capabilities would have been extremely time consuming and incredibly expensive, rendering the project totally impractical. So the new machine had to be based on an existing design, as far as its power plants and dynamics were concerned. At the time, the SAAF operated two main helicopter types – the Aerospatiale (formerly Sud Aviation, now Eurocopter) Alouette III and the Aerospatiale Puma. The Alouette III could not possibly form the basis of a credible attack helicopter – it was not just that it was small, but its powerplant and dynamics system were 1960s technology, clearly outdated, and lacking in power. (An Alouette III powerplant and dynamics system were used as the basis for an engineering and development capability demonstrator for Atlas – now Denel – as a precursor to the Rooivalk programme; designated the Alpha XH-1, it first flew in 1984 and is today preserved at the SAAF Museum at[/b] Air Force Base Swartkops, Pretoria.) Athough the Puma was larger and more powerful than the Alouette III, it had already been displaced on the French production line by its bigger and more powerful offspring, the Super Puma, which first flew in late 1978. This led to South Africa’s developing and successfully executing a project to produce a new helicopter that was a hybrid of the Puma and the Super Puma – the Denel Oryx. The Oryx has a fuselage that is longer than that of the Puma but shorter than that of the Super Puma, and was fitted with the powerplants, dynamics systems, and tail boom of the Super Puma (later, military versions of the Super Puma were redesignated Cougar). The result was and is a helicopter with a greater payload and range capability than the Puma and a greater power-to-weight ratio than the Super Puma/Cougar. In consequence, the Oryx is an ideal transport helicopter for the hot temperatures and high altitudes frequently found in Southern Africa. The Oryx was developed in parallel with the Rooivalk prototypes. Being simpler and cheaper than the Rooivalk, the Oryx programme was completed much more rapidly, the helicopter being unveiled in 1991, and has been the SAAF’s transport helicopter ever since. Thus it was proposed that the Super Puma powerplants and dynamics systems, being made in South Africa for the Oryx programme, be used as the basis for the planned attack helicopter. At least one engineer is known to have proposed that the attack helicopter be based on the engines and dynamics system of the Aerospatiale Dauphin, an intermediate- (light/medium) size helicopter with good manoeuvreability and power, which would have resulted in a smaller, more rapidly developed, and more economical (to develop, buy and operate) system. [b]As the French were allowing South Africa to use the powerplants and dynamics of the Super Puma, they would surely have agreed to the South Africans using the same elements from the Dauphin. However, the SAAF felt that using the same engines and dynamics as the Oryx would simplify logistics and reduce maintenance costs, so the decision was made to use the Super Puma system This is a key reason in Denel’s failure to export the aircraft. No one will buy a warplane whose avionics system is based on 20-year-old computers. Then there is the cost of the aircraft – the direct result of both attempting to make it a world beater and depriving it of eco-nomies of scale by cutting the order to only 12. “The unit cost of the Rooivalk is about $40- million,” says Heitman. This makes it as expensive as the Boeing Apache and the Eurocopter Tiger, the latest models of which have state-of-the-art avionics, and much more expensive than the smaller AgustaWestland Mangusta/Mongoose, and the Russian Mi-24/35 family. Export possibilities have been further reduced by foreign worries about the long-term viability of Denel: will the company still be around in 20 years to continue to support the Rooivalk, if they should buy it? And then there is the fact that the Rooivalk is very heavily dependent on French technology, now the property of Eurocopter, yet Denel tried to export the Rooivalk not only without Eurocopter’s prior agreement and support, but actually in open competition (for example, in Australia) with Eurocopter’s own Tiger. https://m.engineeringnews.co.za/article/what-went-wrong-with-the-rooivalk-2007-06-08-1

dragon2:South-Africa never had the capacity to build on the 12 units of Rooivalk that were manufactured. They don't have the technical expertise, finance or political leverage to make the Rooivalk work. The Rooivalk would be subject to heavy economic sanctions from it's original equipment manufacturers in Europe and America. As hard as it might sound, the aircraft was doomed for failure, it was never a leadership problem. |
SuperSixSeven:This has to be the most ignorant comment I've read this year. The Rooivalk is based on and relies heavily on components and technical expertise from the EU. Especially France. Why shouldn't Nigerians demand that we build our own? The benefits in skills, economics and technical expertise are endless. So why shouldn't we demand it? |
jl115:1 crashed Denel is dead...... No point kicking a dead horse. |
jl115:I see you're still flying with your delusions of grandeur. Good luck with that. Highest this and highest that, yet only 10 are in active service, and all with South-Africa. |

New order for an OCEA survey vessel for Nigeria 12th october 2021 After the delivery in 8 years of 18 ships to the Nigerian Navy, including the NNS LANA, a 60-meter hydrographic research vessel type OSV 190 SC-WB, two 35-meter patrol boats type FPB 110 MKII and two interceptors of 17 m type C-FALCON in 2020, OCEA won an international tender for the supply of a 35-meter hydrographic research vessel type OCEA OSV 115 SC-WB. Vessel’s missions OCEA’s OSV 115 SC-WB type vessel is a hydrographic and oceanographic research vessel from the auxiliary vessels range. Intervening in support of the OSV 190 NNS LANA, it will allow the Nigerian Navy to complete the knowledge of its maritime territory.

shadowprimezero:Ideally, I would have preferred 3 x Ada class corvettes though. Although I know the UCAVs are a more practical option. |
shadowprimezero:I still have my reservations on Turkish military equipment, however if confirmed on the 20th, it would be good news for the air force. |
shadowprimezero:So, you had the last laugh on this argument? ![]() |

shadowprimezero:This looks very beautiful!!! Fantastic effort. I also love the colour they chose. |
jl115:I have no patience for your silly conspiracy theories and crying. The evidence shows Rwanda is doing a very fantastic job in Mozambique. |
Lurker4Long:Go cry elsewhere, your constant whining in this thread is sad, irritating and exhausting. |
Lurker4Long:Keep whining and crying like a clown. Rwanda is doing very good work in Mozambique. |
Lurker4Long:Ridiculous comment, laced with envy. Your envy would be different if it was SAMIM getting all the good press, I bet. |
Lurker4Long:When is South-Africa and SAMIM getting their own credit alert from Total? |
Rwanda to purchase at least 12 Turkish made Bayraktar TB2 attack drones and their first missions could be in the ongoing fight against terrorists and insurgents in Mozambique's Cabo Delgado province.

dragon2:Addressing this MRAP vs IFV question. The mistake made is comparing one against the other, or asking commentators to choose 1 from the two. It's similar to asking us to choose between the MI-17 & MI-35. First, what is an MRAP? An MRAP is an armoured military vehicle designed to provide protection against mines, IEDs and any road side bomb. The MRAP was created in Southern Africa, either South-Africa or Zimbabwe. During the vehicles early days, it was simply known as an APC. Popularity of the word MRAP, the Americans coined the word MRAP, hence the now widespread usage. The earlier American MRAPs were imported South African APCs. The main difference between the MRAP and the regular APC is a higher ground clearance and a V-shaped hull. An IFV or Infantry Fighting Vehicle An IFV is any military vehicle that transports troops to the front line and supports, provides fire support for those troops. So an IFV could be a Toyota pick-up truck with a GPMG gunner or an armoured 8x8 armed with calibers from 30mm and above ATGMs and reconnaissance equipment. As long as that military vehicle transports troops to the frontlines, and provides fire support, it is an IFV. However for the purpose of this discussion, we know which particular IFV our good friend is referring to. The first thing I think military planners in Nigeria consider is cost. So while an IFV is armed with a 30mm, including ATGMs and all the sweet stuffs, a single unit without ammo, training etc could cost up to 2 million USD. While the MRAP or APC is essentially made in Nigeria, costing around 500k USD or lesser per vehicle. So because of funding issues, IED problem, military planners are left with a tough decision to invest in 4 or 5 MRAPs, 1 IFV , Air Support for the air force. This is what I believe is the situation we have seen in the past 4 years. So from the scenario above which would you choose from? |
Odunayaw: ![]() Let's discuss the real issue. |
The Rafale is definitely the sexist fighter jet in existence. Look at this magnificent beast!!

youghs:I 100% agree with this. Military commentators on twitter are guilty of and largely responsible for this. |
Tobiloba24072:IFVs and MBTs are all important. However I have noticed that most people on twitter who tweet in support of the Nigerian military, the likes of Deji and his crew have a habit of overhyping the military equipment. The problem of the military is not the equipment, we have never had an equipment problem. The problems we see time and again is the man. The training of the average Nigerian soldier needs to improve. The machine is nothing without the man. We need to give our officers and men the right training before we talk of equipment. We buy hundreds of millions of dollars worth of equipment every year. We don't have an equipment problem. Take one example, I don't know if a majority of our troops are aware an MRAP is not an invincible vehicle. It is not IED proof, it is designed to get blown up while saving the life of the soldiers. If we don't train our troops well, all the equipment we have bought would have been all for nothing. It's the same way many people especially on twitter kept on calling the Super Tucano a game changer. |
Fynline:It's a NATO patch, but the pilot is flying an MI-35 helicopter. You can see in his glasses the reflection of an MI-35 landing gear, and significantly the S-8 Russian rocket launcher. |
jl115:Plausible argument. |
jl115:I doubt it. Total payment for the 3 x units is 185 million USD. I can't remember where I saw payment has been completed, but I would search for it and post. |
