Osnovno "radno grlo" USAF i palubne LBA avijacije SAD. Mnogobrojan i pouzdan. Treba da ga zameni F-35, ali će F/A-18 leteti još dvadesetak godina sigurno. F/A-18, ranije samo F-18, razvijen je iz YF-17, po specifikaciji za laki lovac s kraja 60ih i početka 70ih. Međutim, u naticanju je pobedio F-16, a tadašnji Northtrop je odlučio da YF-17 dalje razvija, uz povećanje dimenzija i mase. Novi avion, koji je dobio oznaku F-18 kasnije je prihvaćen od DoD i postao je operativan u junu 1981. godine. Znatno kasnije, zmaj aviona je ponovo preprojektovan, sa novim krilom veće površine i povećanjem mase, pa je F-18 dobio novu oznaku F/A-18 i postao osnovni avion palubne avijacije SAD, što je dovelo do prevremenog prizemljenja F-14.

@Kumbor
Zar nije F/A standardna oznaka F/A-18? Preskok koga opisuješ je između "horneta" i "super horneta".


Verzije (oznaka "hornet"):
YF-17 Cobra (prototip lovca razvijen za potrebe projekta LWF),
F/A-18A (lovac/jurišnik, jednosed),
F/A-18B (dvosed za obuku),
F/A-18C (usavršena verzija sa novom pogonskom grupom i novom opremom),
F/A-18D (usavršeni dvosed za obuku),
F-18L (verzija namenjena upotrebi s kopna, razvila ju je kompanija Northrop. Planirano je bilo da to bude izvozna verzija, ali kupci su se odlučili za standardnu verziju F/A-18, tako da verzija F-18L nikada nije ušla u masovnu proizvodnju),
(A) F/A-18A/B (verzija aviona namenjena RV Australije koju po licenci proizvodi GAF),
CF-18A/B (verzija aviona namenjena RV Kanade. Sluţbena oznaka RV Kanade je CF-188A/B Hornet),
EF-18A/B (verzija namenjena RV Španije. U RV Španije jednosedi lovci nose oznaku C.15 a dvosedi za obuku CE.15),
KAF-18C/D (verzija namenjena RV Kuvajta),
F-18C/D ( verzije aviona F/A-18C/D koje su namenjene RV Finske i Švajcarske).

Verzije (oznaka "super hornet"):
F/A-18E (višenamesnki jednosed)
F/A-18F (višenamenski dvosed)
EA-18G Growler (varijanta dvoseda F/A-18F opremljena za elektroničko ratovanje)

AESA nadogradnja se zahuktava za borbene avione F/A-18 Hornet

Datum objave:
20.01.2015

Novi natječaj za nadogradnju radara za nekoliko stotina borbenih aviona Boeing F/A-18 Hornet u sastavu oružanih snaga SAD-a i saveznika, sve se više zahuktava. Northrop Grumman i Raytheon potvrdili su planove ponuda prilagođenih verzija AESA radara za F/A-18 Hornet, uključujući, B, C, D verzije.

Natječaj za AESA radar pokazao je mogućnost nadogradnji i za starije tipove F-18

Raytheon je nedavno obavio testove na APG-79 (V) X radaru, modifikaciji APG-79 koji je instaliran na F/A-18E/F Super Hornetu. U međuvremenu, Northrop nudi skalabilni SABR radar kao nadogradnju za Lockheed Martin F-16, ali može biti prilagođen i za starije F/A-18. Northrop "vjerujemo kako se SABR prirodno uklapa u zrakoplov.

APG-83 SABR donijet će obilježja radara pete generacije zrakoplova na avione F-18 te proširiti operativnost platforme ", kaže Jeff Leavitt, potpredsjednik Nothrop Grumman za sustave borbene avionike. Tržište nadogradnje F/A-18 bilo je ograničeno na varijantu Super Hornet, ali nekoliko nedavnih poteza učinili su nadogradnju vrlo prihvatljivom i izvedivom za starije tipove Horneta.

Američki marinci ponovo uvode u naoružanje "pezionisane" lovce  F/A-18 hornet, to objašnjavaju pomanjkanjem aviona, radi kašnjenja novog F-35. Prema navođenju američkih medija 30kom tih aviona će modernizirati u verziju  “C +”. Marinci imaju, navodno, samo 30% aviona (od 229) F/A-18 hornet operativnih, a trebali bi barem 56%.....

Ameriški marinci obnavljajo “upokojene” lovce F/A-18 hornet

VELIKE ZAMUDE PRI DOBAVI F-35 SPRAVILE V TEŽAVE KORPUS MORNARIŠKE PEHOTE

Korpus mornariške pehote ZDA (USMC) je prisiljen obnavljati upokojene lovce F/A-18 hornet zaradi pomanjkanja letal, kar je posledica velikih zamud pri proizvodnji lovcev 5. generacije F-35, poročajo ameriška televizija Fox News 22. junija 2016.

Korpusu mornariške pehote ZDA (marincem) se je sicer pred leti ponujala možnost naročila lovcev Boeing F/A-18 super hornets, ki bi zapolnili vrzel do prihoda “nevidnih” F-35, vendar je prevladalo mnenje, da je to predraga možnost. Zaradi dolgotrajnih zamud pri dobavi lovcev Locheed Martin F-35, ki so nastale predvsem zaradi številnih “poporodnih težav”, se je sedaj ta odločitev (o nenakupu F/A-18 super hornet oz. čakanje na F-35) za zgrešeno.

Po navedbah ameriških medijev bodo 30 večnamenskih lovcev F/A-18 hornet, ki so bili shranjeni v letalski bazi Davis-Monthan v ameriški zvezni državi Arizona,  nagradili v  “C +” standard na podlagi pogodbe med Boeingom in USMC.

Podatki Korpusa mornariške pehote ZDA kažejo, da je od njihovih 229 večnamenskih lovcev F/A-18 hornet borcev (48 x F/A-18B, 86 x F/A-18C, 95 x F/A-18D) le 30 odstotkov v operativnem stanju, medtem ko jih marinci potrebujejo vsaj 56 odstotkov izpravnih, da so pripravljeni za boj. Hornete bodo v prihodnje nadomestili z desetimi eskadriljami F-35B in štirimi eskadriljami F-35C (ena eskadrilja v ZDA šteje med 18-24 letal). Skupno so sicer pri USMC načrtovali 340 letal F-35B in 80 F-35C.

Od lakog lovca, konkurenta F-16, do osnovnog lovca-bombardera USAF. za AAF, amrince i nosače  Odlična evolucija. F-35 nema šanse da bude ni delom toliko univerzalan, a ni uspešan.

Thrust Vectoring - on an F18 Hornet!  The Story of the NASA Dryden HARV Project:

The F-18 HARV or High Alpha Research Vehicle was a NASA testbed used to study performance at high angles of attack or alpha.  The aircraft flew from 1989 to 1996 in a 3 phased research program that progressively added modifications to the Hornet.  Let’s take a look at the specifications of the F-18 HARV.


Specifications

Length:  56 FT (17.1 M)
Height:  10 FT 6 IN (3.2 M) AT CANOPY
Wingspan: 37 FT 5 IN (11.4M)
Maximum speed: initially Mach 1.8 (1,190 MPH/1,915 KMH), subsonic with later modifications
Phase 1 weight:  31,980 LB, WITH 6,480 LB OF INTERNAL FUEL  14,506 KG / 2939 KG
Phase 2 and 3 weight: 36,099 LB ALSO WITH 6,480 LB OF INTERNAL FUEL  16,374 KG / 2939KG

 
Engines: Thrust Class
Each General Electric
EACH F404-GE-400 turbofan engines, each producing 16,000 LB of thrust  71.17 kN WITH afterburner.


The aircraft that would become the F-18 HARV was actually a pre production F/A-18 and the sixth one ever built.  Having been assigned  Bureau Number 160780, this particular F18 was chosen as a testbed because it had a spin chute installed as the NAVY had used it to evaluate spin performance and recovery.  Under NASAs use the aircraft was designated number 840.

The HARV program was a joint effort between NASA's Dryden, Ames, Langley and Lewis research centers.  By the time NASA received the aircraft, it had been cannibalized for spare parts so extensively by the Navy it was assumed that the aircraft would never fly again.  In fact, the engineers cataloged 400 missing parts and virtually no documentation of the existing wiring system.  To get 840 airworthy, the mechanics and technicians had to cut out the existing wiring, find substitute parts, assemble and rewire the aircraft.  By the time they were done, the words “Silk Purse” were painted on the fuselage, a take on the expression you can't make a silk purse out of a sow’s ear.

Predložena verzija F-18L koju je trebalo da pravi Northrop. Sa letelice bi bila skinuta sva mornarička oprema za poletanje i sletanje, te se računalo na značajno poboljšanje letnih performansi. Verzija je bila namenjena pre svega izvozu:

Quote

A land-based version of the Hornet known as the F-18L was also planned. Since it did not have to carry any equipment for carrier-based operations, the F-18L was expected to be significantly lighter and better-performing than the carrier-based version. Although no orders had actually been received, it was anticipated that the F-18L would be an attractive proposition for those foreign air forces who wanted and could afford an aircraft with greater capabilities than those of the F-5.

As part of the original partnership arrangement between McDonnell Douglas and Northrop, it had been agreed that McDonnell Douglas would be the prime contractor for the carrier-based F-18A version of the Hornet, with Northrop being the prime contractor for the F-18L land-based version. The partnership between these two aerospace giants did not always go smoothly, and strains between the two corporations began to show almost immediately. In particular, a major disagreement arose over sales of the F-18L. It seemed that whenever foreign purchasers showed an interest in acquiring the land-based version of the F-18, McDonnell would immediately mount an active sales effort, putting the carrier-based McDonnell F-18 in direct competition with the land-based Northrop F-18L. Northrop management became very unhappy about what it perceived to be McDD's violation of the terms of their agreement, and in October 1979, a series of lawsuits was launched, with Northrop claiming that McDonnell was unfairly using Northrop technology developed for the F-18L to sell its own F-18A abroad. Northrop also charged that McDonnell was trying to sell Israel a version of the F-18 that competed directly with the Northrop F-18L. Northrop asked the courts to restrain McDonnell from trying to sell to any foreign government any version of the F-18 which took advantage of Northrop technology to the detriment of the latter company. The case dragged on in the courts for years, and was not settled until April of 1985. At that time, it was agreed that McDonnell Douglas would be prime contractor for all existing and future versions of the Hornet, and Northrop terminated all work on its F-18L land-based version.

U.S. Marine Corps F/A-18D Hornets with Marine Fighter Attack Squadron (VMFA) 312 arrive at Marine Corps Air Station Iwakuni, Japan, Oct. 1, 2020. Marines with VMFA-312 and Marine All Weather Fighter Attack Squadron (VMFA (AW)) 533, based out of Marine Corps Air Station Beaufort, South Carolina, take part in a rotational unit deployment program to supplement Marine Aircraft Group (MAG) 12. The deployment enables MAG-12 to maintain its obligation to the Treaty of Mutual Cooperation and Security between Japan and the U.S. while facilitating the safe transition for VMFA-242 from F/A-18D Hornets to F-35B Lightning II.

Thrust Vectoring - on an F18 Hornet!  The Story of the NASA Dryden HARV Project:

The F-18 HARV or High Alpha Research Vehicle was a NASA testbed used to study performance at high angles of attack or alpha.  The aircraft flew from 1989 to 1996 in a 3 phased research program that progressively added modifications to the Hornet.  Let’s take a look at the specifications of the F-18 HARV.


Specifications

Length:  56 FT (17.1 M)
Height:  10 FT 6 IN (3.2 M) AT CANOPY
Wingspan: 37 FT 5 IN (11.4M)
Maximum speed: initially Mach 1.8 (1,190 MPH/1,915 KMH), subsonic with later modifications
Phase 1 weight:  31,980 LB, WITH 6,480 LB OF INTERNAL FUEL  14,506 KG / 2939 KG
Phase 2 and 3 weight: 36,099 LB ALSO WITH 6,480 LB OF INTERNAL FUEL  16,374 KG / 2939KG

 
Engines: Thrust Class
Each General Electric
EACH F404-GE-400 turbofan engines, each producing 16,000 LB of thrust  71.17 kN WITH afterburner.


The aircraft that would become the F-18 HARV was actually a pre production F/A-18 and the sixth one ever built.  Having been assigned  Bureau Number 160780, this particular F18 was chosen as a testbed because it had a spin chute installed as the NAVY had used it to evaluate spin performance and recovery.  Under NASAs use the aircraft was designated number 840.

The HARV program was a joint effort between NASA's Dryden, Ames, Langley and Lewis research centers.  By the time NASA received the aircraft, it had been cannibalized for spare parts so extensively by the Navy it was assumed that the aircraft would never fly again.  In fact, the engineers cataloged 400 missing parts and virtually no documentation of the existing wiring system.  To get 840 airworthy, the mechanics and technicians had to cut out the existing wiring, find substitute parts, assemble and rewire the aircraft.  By the time they were done, the words “Silk Purse” were painted on the fuselage, a take on the expression you can't make a silk purse out of a sow’s ear.

F-18 HARV

During the late 1980s, NASA decided to deepen its understanding of flight at high angles of attack, or alpha. For this purpose, it created the High Angle-of-Attack Technology Program, or HATP.

A unique aircraft was selected among thousands to participate in the program. It was the infamous F-18 Hornet. Previously used by the Navy for testing purposes, the chosen example was the sixth Hornet built by McDonnell Douglas Corporation.

However, the aircraft had been severely cannibalized for spare parts throughout the years, and it was so mangled that the Navy believed it would never fly again.

Still, the engineers carried on and believed in what would eventually be remembered as the legendary F-18 High Angle-of-Attack Research Vehicle, providing the foundations on how to handle all future American fighter aircraft...

Australija ima 14 lovaca F/A-18 Hornet u radnom stanju koji bi mogli da budu prebačeni u Ukrajinu

Početkom leta je objavljeno da bi Australija mogla da prebaci 41 borbeni avion četvrte generacije F/A-18 Hornet u Ukrajinu. Kako se ispostavilo, Kraljevsko vazduhoplovstvo ima daleko manje aviona u ispravnom stanju.

Novinari časopisa The Australian Financial Review dobili su pristup izveštaju o inventaru američkih borbenih aviona koje drže Kraljevsko australijsko vazduhoplovstvo. Popis je izvršila američka avio-kosmička kompanija RAVN na zahtev Ukrajine, koji je pre nekoliko nedelja objavio ukrajinski ambasador u Australiji Vasil Mirošničenko.

Saznalo se da ako Australija zaista želi da preda F/A-18 Hornet ukrajinskom ratnom vazduhoplovstvu, samo 14 letelica je u ispravnom stanju. Među njima je 11 jednoseda i tri dvoseda.

Svaki avion je leteo više od 3.000 sati, što je otprilike polovina ograničenja. Istovremeno, nije isključeno da letelicama F/A-18 Hornet može biti produžen vek u službi, pri čemu bi Ukrajina potencijalno mogla da koristi F/A-18 Hornet dve godine.

Španija će potrošiti 55 miliona dolara da produži vek trajanja borbenih aviona F/A-18 Hornet do sredine sledeće decenije

Španija namerava da uloži nekoliko desetina miliona evra u produženje radnog veka lovaca F/A-18 Hornet četvrte generacije. Vlada zemlje je odobrila investiciju.

Španija će potrošiti oko 50 miliona evra (55 miliona dolara) za kupovinu rezervnih delova da bi potrošili životni vek aviona. Ovo će omogućiti lovcima F/A-18 Hornet, koji u Španiji imaju oznaku EF-18M, da lete do 2035. godine, uprkos glasinama o povlačenju iz upotrebe do 2030. godine.

Iberijska vlada je već počela da rashoduje stari F/A-18 Hornet, koji je stacioniran u vazdušnoj bazi Gando na Gran Kanariji. Zameniće ih evropski lovci Eurofighter Typhoon.

Pre dve godine Španija je potpisala ugovor sa Erbasom. Madrid je naručio 20 aviona četvrte generacije. Posao je vredeo oko 2 milijarde evra (2,2 milijarde dolara). Isporuke borbenih aviona Eurofighter Typhoon počeće 2026. godine.
